Transmission Control Protocol/Internet Protocol (TCP/IP) is the combination of a networking protocol (TCP) and computer addressing (IP) that makes it possible for computers to communicate across the Internet.
Internet protocols: hostname, HTTP, HTTPS, IP, IP Address, MQTT, MQTTS, MQTTWSS, protocol, TCP, TCP/IP, TLS, WebSocket
Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
FairCom's SQL engine is ANSI compliant and has almost all SQL features up through the SQL:2003 standard.
JavaScript Object Notation (JSON) is a simple format for representing data. It requires very little markup and is flexible enough to represent the majority of data structures. It is self-describing, which makes it ideal for schemaless applications and search. It can optionally be paired with a schema to define an expected structure.
Indexed Sequential Access Method (ISAM) is FairCom's primary ACE API. ISAM uses the Record Buffer Method, which gives the application full control over the contents of the entire record buffer to store structured or unstructured data.
FairCom's ISAM API provides full control over record processing. This allows developers to implement data processing algorithms that are tailored to precise application needs, and this allows an application to achieve unrivaled performance. FairCom's ISAM API works best in the C and C++ languages.
FairCom ACE APIs include ISAM, CTDB, and Low-level ACE API.
Open Platform Communications Unified Architecture (OPC UA) is a machine-to-machine communication protocol for industrial automation. OPC UA is the latest, easiest, and most robust protocol from the OPC Foundation.
The FairCom Edgeprovides a connector to OPC UA to bridge data from OPC UA devices to other protocols, including MQTT, JSON, and SQL.
Hypertext Transfer Protocol (HTTP) is a standard request-response protocol that works on top of TCP/IP. It allows a client computer to send a request to a server computer, which in turn, replies to the request. The purpose of HTTP is to allow software to ask questions and receive answers.
Secure Hypertext Transfer Protocol (HTTP) is the HTTP protocol running over TLS. It provides secure request-response communications between computers.
Secure Message Queueing Telemetry Transport (MQTTS) is the MQTT protocol running over TLS. It provides secure messaging between computers.
Transport Layer Security (TLS) is a secure way for computers to communicate. It uses encryption, a certificate file , and a private key file to create secure communications between computers. TLS was formerly called Secure Sockets Layer (SSL). FairCom products support TLS 1.3, which is the latest version.
WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.

The Record Buffer Method is a technique for an application (typically C or C++) to retrieve a record from a file on disk and load it into an application's record buffer for reading and editing. When an application has finished editing the buffer, it writes the buffer back to disk. Because an application allocates a buffer in RAM, the Record Buffer Method is the fastest way to map data on disk to data in an application.
An application typically uses an API, such as FairCom's ISAM or CTDB API, to manage the process of reading and writing records to disk. A mature API can batch process multiple records at a time using arrays of buffers. The Record Buffer Method is exceptionally fast, efficient, and provides predictable performance because it transfers data directly from RAM to disk and vice versa.

A bidirectional connector can receive data from a device and send data to a device. In other words, it works as an input, an output, or both.
In FairCom Edge, when an input connector receives data, the FairCom server converts it into a record and inserts it into the integration table that is mapped to the input. When an output is connected to an integration table, the FairCom server converts the record to the format used by the output and it delivers resulting data to the output. For example, MQTT is a bidirectional connector because it receives input messages from MQTT publishers and delivers output messages to MQTT subscribers.
An integration table is not controlled by any one connector. Many input and outputs can be mapped to the same integration table.
An integration table is an enhanced database table used by FairCom Edge and FairCom MQ. It is enhanced to do the following things automatically: collect data from input connectors, add time series data, transform data, and push data to output services with guaranteed delivery.
BIGINT is a FairCom database field type containing a signed integer number, such as -9223372036854770000. It is stored in a record as a signed 64-bit integer number with a range from -9,223,372,036,854,770,000 to 9,223,372,036,854,770,000.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
BINARY is a FairCom database field type containing a binary value. It is stored in a record as a series of bytes . It has a fixed length from 1 to 65,500 bytes, which is stored once in the table's header. If a value is smaller than its fixed length, the server uses padding to fill in missing bytes at the end.

Padding is a feature of the CHAR and BINARY field types. These fieldtypes have a fixed-length that is specified when they are created. Padding allows an application to fill part of the value of one of these fields and the server will fill out the remaining length with a pad character. The pad character defaults to the 0x00 byte. Each table can have its own user-defined pad character.
A binary record is a fixed-length or variable-length record stored in a file or table as a single binary value. An application controls the value of each byte in the record. Binary records are stored and retrieved from files or tables using the Record Buffer Method. A server indexes binary records using byte offset techniques.
In contrast, a SQL database allows an application to read and write fields in a record. The SQL database converts field values into the binary record that it stores in a table. A SQL database prevents an application from directly accessing the binary value of a record.
The FairCom database engine simultaneously supports binary records and SQL records. Through FairCom's ISAM, CTDB, and Low-level ACE API, an application can read and write directly to binary records using the Record Buffer Method. This approach allows an application to achieve unequaled data processing speed. Through FairCom's JSON DB APIand SQL APIs, an application can read and write fields in a record. This makes it easy for an application to process data in complex ways. An application can use these APIs simultaneously to achieve optimal performance and capability.

If https://localhost:8443/ does not work, try https://127.0.0.1:8443/ . Also make sure the FairCom server is running.
When running the Google Chrome web browser and the FairCom server on different computers, change localhost to the hostname or IP Address of the server where the FairCom server is running.
A hostname uniquely identifies a computer on a TCPIP network.
Each computer in a TCP/IP network usually has a hostname assigned to it by a DNS server. When software tries to open a URL, it connects to a DNS server, retrieves the actual IP Address and uses it to connect to the computer.
Internet Protocol Address (IP Address) uniquely identifies each computer in a TCP/IP network. An IP Address has a standard format, such as 127.0.0.1.
A database is a set of data that is managed by a database server. A database contains data that is organized into tables, records, and fields. A database is a huge composite data type that represents a group of interconnected objects. A database allows records to be joined together for querying, searching, and processing by users, applications, and services.
A database is a security container that controls which accounts have permissions to access specific data.
A database server manages data for applications, users, and services. It is the engine that enables records to be joined together for querying, searching, and processing by users, applications, and services.
A database server provides transactions that allows multiple accounts to connect to the server and access all data simultaneously as if each account is the only one working with the data. Transactions allow multiple actions to be run as a group to ensure data is consistent, durable, atomic, and isolated. A transaction reports success only if all parts of it succeed and if any part fails, the database server rolls back all the changes.
A database server also provides highly available services that index, query, update, backup, encrypt, and replicate data.
A database server manages one or more databases and enforces the security permissions of those databases.
Data is a set of values that are collected, cataloged, indexed, and organized into information for querying, searching, and processing by users, applications, and services.
A database table defines a specific type of record, such as a person's data. A table contains zero or more records. A record contains two or more fields.
In the JSON DB API, a table must always have an "id" field to uniquely identify each record. A table is similar to a collection in a NoSQL database.
A FairCom table may have up to 2500 fields and zero or more of those fields may have a JSON type. Each field (or group of fields) may be indexed by one or more indexes with a maximum of 500 indexed fields. One or more individual properties inside a JSON field may also be indexed.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
In a FairCom server, data is stored in fields, records, tables, and databases. A field contains a specific type of data, such as a person's name or a data collection timestamp. Each field has a field type. A record contains one or more fields. A table contains zero or more records. Each field has a predefined data type, such as JSON, INTEGER, NUMERIC, VARCHAR, DATE, TIME, TIMESTAMP, etc.

Edge is also known as Edge of the Network. The edge is the furthest point in a network, such as smart phones, IoT sensors, smart appliances, factory equipment, vehicles, cloud gateway services, etc. The edge can be mobile, such as a vehicle, or it can be a fixed location, such as a factory, hospital, office, store, building, data center, etc. In simple terms, the edge is any location that is not in the Cloud.
A computer network connects computers so they can communicate with each other. The Internet is the ultimate computer network because it is a network of networks.
An enriching transform is one of the primary forms of transforms. It combines data from multiples sources to create more valuable data — for example, looking up data in a database to add new properties to a JSON document or running a machine learning algorithm on the data in a JSON document to classify it and storing the results in the document.
Other types of transforms include reformatting transform and reshaping transform.
A data transformation converts one form of data into another. The primary forms of data transformations include enriching transforms, reformatting transforms, and reshaping transforms. A transform may combine any or all types of transformations.
A transform in FairCom Edge is a process that uses one or more transform services to transform data in an integration table. Each integration table has a configurable transform process that runs each time a record is inserted into that table. The transform process may contain zero or more transform steps. Each step runs a transform method supplied by a transform service. Each step can send its output as the input of a subsequent transform step.
By chaining together transform services FairCom Edge can convert the initial data into one or more output formats, shapes, enrichments, and generated results. So when a record is inserted into an integration table, the table's transform process can take the contents of the "source_payload" field and update the transforms fields "t1" through "t9" with a wide variety of transformed results, such as JSON documents, XML documents, binary data formats, modified or generated images, metadata, results of machine learning, and so forth. Output services can use any of these fields as their source of data making it easy for data to come into FairCom Edge in one format and go out to many different services in different formats.
FairCom Edge ships with several transform plugins that provide a variety of transform services, such as converting Siemen’s native binary PLC data into JSON, converting JSON into tables, converting tables into JSON, transforming the structure of JSON documents, transforming the values of JSON properties, and more.
Reformatting transform is one of the primary forms of Data Transforms that changes how the data is stored as bit and bytes — for example, reformatting a binary BSON document to a textual JSON document.
Other types of transforms include reshaping transform and enriching transform.
Reshaping transform is one of the primary forms of Data Transforms that changes how the data is organized — for example, converting deeply nested data in an object into a flat set of properties in a record.
Other types of transforms include reformatting transform and enriching transform.

Each of FairCom's products is a server process that runs on a computer. The server listens for requests and returns responses.
All FairCom products support the jsonAction protocol running over the HTTP and WebSocket protocols, and support SQL and ISAM protocols running over TCP/IP. FairCom MQ and FairCom Edge products also support the MQTT protocol, which pushes messages from publishers to subscribers.
The FairCom server is unique in that it can be embedded in an application. This immediately extends the capabilities of an application with server features, such as messaging, database management, SQL queries, JSON queries, data transforms, and connectors to other protocols.
The JSON Action Protocol (jsonAction) is like REST, jsonAction is a standard way of using JSON to execute actions on remote computers by sending a JSON Action request to a server and receiving back a JSON response. All information needed in a request and its response is included in the JSON. This allows jsonAction to work over any protocol including HTTP, HTTPS, WS, WSS, MQTT, MQTTS, etc.
jsonAction improves on REST by putting all request information in JSON. In contrast, REST spreads request information across a URL, query string, HTTP header, HTTP verb, and HTTP payload. Similarly, jsonAction puts all response information in JSON, whereas REST spreads response information across the HTTP header and HTTP payload. Lastly, REST only works over HTTP whereas, jsonAction works over any protocol including asynchronous protocols.
Hypertext Transfer Protocol (HTTP) is a standard request-response protocol that works on top of TCP/IP. It allows a client computer to send a request to a server computer, which in turn, replies to the request. The purpose of HTTP is to allow software to ask questions and receive answers.
WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.
Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
FairCom's SQL engine is ANSI compliant and has almost all SQL features up through the SQL:2003 standard.

A connector allows applications and hardware to communicate with each other.
The FairCom Edge server provides a number of connectors that enable the server to communicate with devices, equipment and software. For example, the FairCom EdgeOPC UA connector, enables FairCom Edge to use the OPC UA protocol to connect to any OPC UA enabled device to retrieve data.
There are input connectors, output connectors, and bidirectional connectors that support both input and output from and to the same device. There are also connectors designed for different types of solutions, such as an enterprise connector, IT connector, and IoT connector.
A protocol is a defined set of rules for communicating between systems. There are hundreds of communication protocols used by IT, OT, IoT, and IIoT systems. A major cost of integrating systems is writing software or buying hardware to perform the translations required to communicate between systems.
An Integration Hub, such as FairCom Edge, is designed to reduce integration costs by providing built-in translations between protocols. Communication protocols can be categorized as a push protocol, pull protocol, or query protocol. Push, pull, and query protocols are traditionally incompatible with each other, but an Integration Hub, such as FairCom Edge, is designed to automatically bridge across all types of protocols.
In a FairCom server, data is stored in fields, records, tables, and databases. A field contains a specific type of data, such as a person's name or a data collection timestamp.

Internet Protocol Address (IP Address) uniquely identifies each computer in a TCP/IP network. An IP Address has a standard format, such as 127.0.0.1.
Tables created by the JSON DB API have an identifier (ID) field known as "id" that uniquely identifies each record. It is the primary key of the record. It is stored as a BIGINT, which is a signed, 64-bit integer. When records are inserted, the FairCom database server automatically populates the value of the "id" field with a unique integer value.
The JSON DB API uses JSON over HTTP to manage databases, tables, indexes, records, queries, cursors, and transactions. It is available in all FairCom products.
This API is part of FairCom's family of JSON APIs.
A primary key is the primary identifier of a record in a database table. It is the primary way to look up records in a table. It is always indexed with a unique, non-null index that ensures each inserted record is uniquely identified. A primary key index includes one or more fields in a table.
The best practice is for a primary key to consist of one field named "id" that the server automatically populates with a unique identifier each time a record is inserted.
BIGINT is a FairCom database field type containing a signed integer number, such as -9223372036854770000. It is stored in a record as a signed 64-bit integer number with a range from -9,223,372,036,854,770,000 to 9,223,372,036,854,770,000.
An input connector is a connector that retrieves data from a device and brings it into a server.
In FairCom Edge, an input connector converts a device protocol into JSON, and stores the JSON into a record in an integration table . Each time a record is stored in an integration table, FairCom Edge can automatically reformat, reshape, enrich, and deliver the resulting data to one or more output connectors.
Many input connectors of any type can be connected to the same integration table; thus, many input connectors can gather data from many sources and insert the data into the same integration table.
A connector allows applications and hardware to communicate with each other.
The FairCom Edge server provides a number of connectors that enable the server to communicate with devices, equipment and software. For example, the FairCom EdgeOPC UA connector, enables FairCom Edge to use the OPC UA protocol to connect to any OPC UA enabled device to retrieve data.
There are input connectors, output connectors, and bidirectional connectors that support both input and output from and to the same device. There are also connectors designed for different types of solutions, such as an enterprise connector, IT connector, and IoT connector.
JavaScript Object Notation (JSON) is a simple format for representing data. It requires very little markup and is flexible enough to represent the majority of data structures. It is self-describing, which makes it ideal for schemaless applications and search. It can optionally be paired with a schema to define an expected structure.
An integration table is an enhanced database table used by FairCom Edge and FairCom MQ. It is enhanced to do the following things automatically: collect data from input connectors, add time series data, transform data, and push data to output services with guaranteed delivery.
INTEGER is a FairCom database field type containing a signed integer number, such as -2147483648. It is stored in a record as a signed 32-bit integer number with a range from -2,147,483,648 to 2,147,483,647.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
An integration table is an enhanced database table used by FairCom Edge and FairCom MQ. It is enhanced to do the following things automatically: collect data from input connectors, add time series data, transform data, and push data to output services with guaranteed delivery.
The Internet is a global network of networks that allows computers to communicate with each other. This is possible because it defines a standard set of communication protocols.
A hostname uniquely identifies a computer on a TCPIP network.
Each computer in a TCP/IP network usually has a hostname assigned to it by a DNS server. When software tries to open a URL, it connects to a DNS server, retrieves the actual IP Address and uses it to connect to the computer.
Hypertext Transfer Protocol (HTTP) is a standard request-response protocol that works on top of TCP/IP. It allows a client computer to send a request to a server computer, which in turn, replies to the request. The purpose of HTTP is to allow software to ask questions and receive answers.
Secure Hypertext Transfer Protocol (HTTP) is the HTTP protocol running over TLS. It provides secure request-response communications between computers.
Internet Protocol (IP) is the official Internet addressing scheme for uniquely identifies computers in network communications, see RFC 792. IP makes it possible to create networks of networks of computers.

A protocol is a defined set of rules for communicating between systems. There are hundreds of communication protocols used by IT, OT, IoT, and IIoT systems. A major cost of integrating systems is writing software or buying hardware to perform the translations required to communicate between systems.
An Integration Hub, such as FairCom Edge, is designed to reduce integration costs by providing built-in translations between protocols. Communication protocols can be categorized as a push protocol, pull protocol, or query protocol. Push, pull, and query protocols are traditionally incompatible with each other, but an Integration Hub, such as FairCom Edge, is designed to automatically bridge across all types of protocols.
Transmission Control Protocol (TCP) is a standard networking protocol that allows computers to communication, see RFC 793.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the combination of a networking protocol (TCP) and computer addressing (IP) that makes it possible for computers to communicate across the Internet.
Internet protocols: hostname, HTTP, HTTPS, IP, IP Address, MQTT, MQTTS, MQTTWSS, protocol, TCP, TCP/IP, TLS, WebSocket
Transport Layer Security (TLS) is a secure way for computers to communicate. It uses encryption, a certificate file , and a private key file to create secure communications between computers. TLS was formerly called Secure Sockets Layer (SSL). FairCom products support TLS 1.3, which is the latest version.
Uniform Resource Locator (URL) is a standard way for uniquely addressing resources on a network. A URL is an Internet standard that uses the following pattern: protocol://domainName:portNumber/resource.
Common FairCom URLs include https://docs.faircom.com/docs/ and https://localhost:8443/.
WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.
WebSocket Secure (WSS)is the secure version of WebSocket. It uses TLS to create secure communications.
Internet of Things (IoT) uses Internet protocols to connect things to software. Things include devices, equipment, appliances, vehicles, and so forth.
Each thing must contain an embedded computer processor and must use an IoT protocol, such as MQTT, to communicate with software.
Since 2014, MQTT has become the standard Internet protocol for IoT. MQTT is necessary because devices need to push information when it is created, such as a status update, an alert, telemetry, or a command. MQTT is used in IoT because HTTP is a request/response protocol that cannot push information.

Indexed Sequential Access Method (ISAM) is FairCom's primary ACE API. ISAM uses the Record Buffer Method, which gives the application full control over the contents of the entire record buffer to store structured or unstructured data.
FairCom's ISAM API provides full control over record processing. This allows developers to implement data processing algorithms that are tailored to precise application needs, and this allows an application to achieve unrivaled performance. FairCom's ISAM API works best in the C and C++ languages.
FairCom ACE APIs include ISAM, CTDB, and Low-level ACE API.
Advanced C (core) Engineering (ACE), see ACE APIs.
The Record Buffer Method is a technique for an application (typically C or C++) to retrieve a record from a file on disk and load it into an application's record buffer for reading and editing. When an application has finished editing the buffer, it writes the buffer back to disk. Because an application allocates a buffer in RAM, the Record Buffer Method is the fastest way to map data on disk to data in an application.
An application typically uses an API, such as FairCom's ISAM or CTDB API, to manage the process of reading and writing records to disk. A mature API can batch process multiple records at a time using arrays of buffers. The Record Buffer Method is exceptionally fast, efficient, and provides predictable performance because it transfers data directly from RAM to disk and vice versa.

In contrast, the jsonAction protocol is simpler and easier to use because it encapsulates all information in JSON, and it works over any communication protocol.
JavaScript Object Notation (JSON) is a simple format for representing data. It requires very little markup and is flexible enough to represent the majority of data structures. It is self-describing, which makes it ideal for schemaless applications and search. It can optionally be paired with a schema to define an expected structure.
The Low-level ACE API is FairCom's lowest level API. It provides total control over every detail of index and table creation and management. It requires the most code and provides maximum control for maximum server-side performance. It works best in the C and C++ languages.
FairCom ACE APIs include ISAM, CTDB, and Low-level ACE API.
Indexed Sequential Access Method (ISAM) is FairCom's primary ACE API. ISAM uses the Record Buffer Method, which gives the application full control over the contents of the entire record buffer to store structured or unstructured data.
FairCom's ISAM API provides full control over record processing. This allows developers to implement data processing algorithms that are tailored to precise application needs, and this allows an application to achieve unrivaled performance. FairCom's ISAM API works best in the C and C++ languages.
FairCom ACE APIs include ISAM, CTDB, and Low-level ACE API.
The c-tree Database API (CTDB API) is FairCom's database API in the ACE family of APIs. It provides high performance with less code than the FairCom's ISAM API. The CTDB API introduces database concepts that are compatible with SQL. It requires records to contain predefined field structures. FairCom's CTDB API provides full control over record processing. This allows developers to implement data processing algorithms that are tailored to precise application needs, and this allows an application to achieve unrivaled performance. FairCom's CTDB API works well in a variety of languages, such as C, C++, Java, C#, and Visual Basic.

LVARBINARY is a FairCom database field type containing a variable-length binary value. It is stored as a variable-length sequence of bytes up to 2 Gigabytes in length. Each LVARBINARY field in each record includes a four-byte length header.
LVARCHAR is a FairCom database field type containing a variable-length string, such as "my string". It is stored as a variable-length sequence of bytes up to 2 Gigabytes in length. Each LVARCHAR field in each record includes a four-byte length header. The bytes are interpreted as UTF-8 encoded characters.
Modbus is a binary server/client communication protocol developed and published by Modicon for transmitting data to and from electronic devices over a serial bus or TCP/IP network.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the combination of a networking protocol (TCP) and computer addressing (IP) that makes it possible for computers to communicate across the Internet.
Internet protocols: hostname, HTTP, HTTPS, IP, IP Address, MQTT, MQTTS, MQTTWSS, protocol, TCP, TCP/IP, TLS, WebSocket
MONEY is a FairCom database field type containing a signed decimal number, such as -12345678900.0001. It is stored in a record as a signed, fixed-point decimal number with 32 digits of precision. It consumes 19 bytes of storage. The "scale" property specifies 2 or 4 digits to the right of the decimal point. The remainder of the precision is to the left of the decimal point.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
MQ Explorer is FairCom's user interface for managing its MQTT broker, which is part of the FairCom Edge and FairCom MQ products.
It provides a dashboard for tracking MQTT clients, topics, and messages. It also includes an MQ client that can publish and subscribe to messages. It also includes API Explorer for configuring the product.
FairCom browser-based applications are optimized to run in the Google Chrome browser. If the browser is running on the same computer as the FairCom server, you can open FairCom's browser-based applications using the following URL: https://localhost:8443/. You can also run the application from any computer by replacing localhost in the URL with the hostname or IP Address of the FairCom server.
This URL launches a menu for running the FairCom browser-based applications. It works when a Google Chrome web browser runs on the same computer where the FairCom server is running.
Google Chrome may complain that your connection is not private. To resolve this issue see Solve certificate security problems in Google Chrome. FairCom browser-based applications are safe and become more secure when you replace FairCom's default certificate with your own security certificate.
If https://localhost:8443/ does not work, try https://127.0.0.1:8443/ . Also make sure the FairCom server is running.
When running the Google Chrome web browser and the FairCom server on different computers, change localhost to the hostname or IP Address of the server where the FairCom server is running.
A hostname uniquely identifies a computer on a TCPIP network.
Each computer in a TCP/IP network usually has a hostname assigned to it by a DNS server. When software tries to open a URL, it connects to a DNS server, retrieves the actual IP Address and uses it to connect to the computer.
Internet Protocol Address (IP Address) uniquely identifies each computer in a TCP/IP network. An IP Address has a standard format, such as 127.0.0.1.

WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.
FairCom's Navigational (NAV) APIs use the Record Buffer Method to navigate records forward and backward within a file in table or index order. These APIs include FairCom's ISAM, CTDB, and JSON DB API.
The Record Buffer Method is a technique for an application (typically C or C++) to retrieve a record from a file on disk and load it into an application's record buffer for reading and editing. When an application has finished editing the buffer, it writes the buffer back to disk. Because an application allocates a buffer in RAM, the Record Buffer Method is the fastest way to map data on disk to data in an application.
An application typically uses an API, such as FairCom's ISAM or CTDB API, to manage the process of reading and writing records to disk. A mature API can batch process multiple records at a time using arrays of buffers. The Record Buffer Method is exceptionally fast, efficient, and provides predictable performance because it transfers data directly from RAM to disk and vice versa.
Indexed Sequential Access Method (ISAM) is FairCom's primary ACE API. ISAM uses the Record Buffer Method, which gives the application full control over the contents of the entire record buffer to store structured or unstructured data.

Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
FairCom's SQL engine is ANSI compliant and has almost all SQL features up through the SQL:2003 standard.
An output connector is a connector that a server sends to a device, equipment, protocol, or software.
FairCom Edge provides multiple output connectors that connect to Thingworx, SQL, MQTT, etc. Each output connector is connected to an integration table. Each time a record is inserted into the integration table, FairCom Edge sends that record to the output connector. The output connector retrieves data from the inserted record, and delivers it to devices, equipment, and software that are registered to receive the data.
Many output connectors of any type can be connected to the same integration table; thus, each record inserted into an integration table can be delivered to many outputs.
For example, FairCom Edge's MQTT connector allows any MQTT 3 and MQTT 5 client to subscribe to any topic. Each topic is assigned to an integration table. Each MQTT message sent to the topic is stored in the corresponding integration table and then is automatically published to all subscribers of that topic. Additional connectors can be mapped to the same integration table to deliver data ot other solutions, such as ThingWorx.
A connector allows applications and hardware to communicate with each other.
The FairCom Edge server provides a number of connectors that enable the server to communicate with devices, equipment and software. For example, the FairCom EdgeOPC UA connector, enables FairCom Edge to use the OPC UA protocol to connect to any OPC UA enabled device to retrieve data.
There are input connectors, output connectors, and bidirectional connectors that support both input and output from and to the same device. There are also connectors designed for different types of solutions, such as an enterprise connector, IT connector, and IoT connector.
An integration table is an enhanced database table used by FairCom Edge and FairCom MQ. It is enhanced to do the following things automatically: collect data from input connectors, add time series data, transform data, and push data to output services with guaranteed delivery.

Padding is a feature of the CHAR and BINARY field types. These fieldtypes have a fixed-length that is specified when they are created. Padding allows an application to fill part of the value of one of these fields and the server will fill out the remaining length with a pad character. The pad character defaults to the 0x00 byte. Each table can have its own user-defined pad character.
CHAR is a FairCom database field type containing a fxed-length, padded string value, such as "my string". It is stored in a record as a series of UTF-8 characters. It has a fixed-length between 1 and 65,500 bytes, which is stored once in the table's header. If a value is smaller than its fixed length, the server uses padding to fill in missing bytes at the end.
BINARY is a FairCom database field type containing a binary value. It is stored in a record as a series of bytes . It has a fixed length from 1 to 65,500 bytes, which is stored once in the table's header. If a value is smaller than its fixed length, the server uses padding to fill in missing bytes at the end.
Programmable Logic Controller (PLC) is an industrial computer with electrical inputs and outputs that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
A plugin is a library that a server loads dynamically to provide one or more services. A plugin adds capabilities to the server.
FairCom Edge comes with multiple plugins. One plugin collects OPC UA data, another collects Modbus data, another transforms Siemens UDT into JSON, another sends data to ThingWorx, and so forth. Customers can also create plugins. FairCom plugins have a standard interface that is implemented in C or C++ and compiled as a Windows DLL, a linux SO, or a MacOS dylib.
A FairCom server can be configured to load multiple instances of a plugin library and configure each instance separately, such as configuring it to use different ports and different settings. Therefore, a plugin can be loaded multiple times to provide its set of services multiple times. This is useful to scale the throughput of a plugin or to specify the settings of each plugin instance to provide specialized services. Additionally, a single plugin may implement multiple services.
A plugin service is a service provided by a plugin. A single plugin can provide one or more services.
A service is a capability provided by the server. A FairCom server has many built-in services, including the ability to listen, process, and respond to SQL statements over a TCP/IP port, and the ability to respond to JSON action commands over HTTP and WS. FairCom Edge provides additional services. A service can implement a protocol, such as MQTT, OPC UA, Modbus, and ThingWorx. A service can implement data transformations, such as converting binary data into JSON. Additional services can be added through plugins.

A primary key is the primary identifier of a record in a database table. It is the primary way to look up records in a table. It is always indexed with a unique, non-null index that ensures each inserted record is uniquely identified. A primary key index includes one or more fields in a table.
The best practice is for a primary key to consist of one field named "id" that the server automatically populates with a unique identifier each time a record is inserted.
A private key is the secret required by TLS to prove the identity of a computer. It is the private key of the public-private key pair that is used to create a computer's digital identity certificate. It is stored in a private key file.
Transport Layer Security (TLS) is a secure way for computers to communicate. It uses encryption, a certificate file , and a private key file to create secure communications between computers. TLS was formerly called Secure Sockets Layer (SSL). FairCom products support TLS 1.3, which is the latest version.
A public-private key pair is a pair of asymmetrical keys. The private key can encrypt a secret and only the public key can decrypt that secret. This also works in reverse where the public key can encrypt a secret and only the private key can decrypt that secret.
A digital identity certificate is an electronic document used by TLS to allow an application, such as a web browser, MQTT client, or server, to know when it is communicating with an intended computer rather than a fraudulent computer impersonating the intended computer.
A private key file is a file that contains the private key required by TLS to prove the identity of a computer. The private key file contains the private key of the public-private key pair that is used to create a computer's digital identity certificate . The private key file typically has the extension, .key, such as server.key or client.pem.

A protocol is a defined set of rules for communicating between systems. There are hundreds of communication protocols used by IT, OT, IoT, and IIoT systems. A major cost of integrating systems is writing software or buying hardware to perform the translations required to communicate between systems.
An Integration Hub, such as FairCom Edge, is designed to reduce integration costs by providing built-in translations between protocols. Communication protocols can be categorized as a push protocol, pull protocol, or query protocol. Push, pull, and query protocols are traditionally incompatible with each other, but an Integration Hub, such as FairCom Edge, is designed to automatically bridge across all types of protocols.
A push protocol allows a client to push messages to a server and the server pushes these messages to clients. The server may offer various guarantees of message delivery.
Push protocols have the advantage of sending notifications when events occur. This is particularly important for environments that need to be alerted when critical events occur, such as medical equipment emergencies and equipment failure in manufacturing. Pushing data is also useful for sending telemetry when it is available or when it has changed rather than repeatedly polling a device for the latest value.
MQTT is a push protocol. At any time, a client can publish an MQTT message to any topic on an MQTT broker. Any MQTT client can subscribe to any topic on an MQTT broker and the broker pushes received messages to subscribing clients. MQTT 3 can only push messages. MQTT 5 has an option to reply to pushed messages.
A pull protocol is a request/response protocol. Client software sends a request to a server to ask for data. The server responds by sending data to the client. A pull protocol asks a specific question to get back the current value of a specific type of information, such as the value of a device register, the current time, or the profile of a specific user.
In IoT, pull protocols include OPC UA and Modbus. In IT, pull protocols include REST, JSON/HTTP, and SQL.
In contrast, a query protocol differs from a pull protocol in that it asks for some combination of filtered, aggregated, and joined sets data that are stored in a repository of data, such as a database.
A query protocol is a variation of a request/response protocol. Client software sends a query request to a server to ask for data. The server responds by sending data to the client. A query protocol asks for some combination of filtered, aggregated, and joined sets data that are stored in a repository of data, such as a database.
In contrast, a pull protocol asks the current value of a specific type of information, such as the value of a device register, the current time, or the profile of a specific user.
In IT, query protocols include SQL, REST, GraphQL, and JSON action.
A protocol transformation converts between protocols, such as converting from the Modbus protocol to MQTT. During a protocol transformation, data is often transformed as well.
FairCom Edge converts a variety of protocols into JSON and stores the JSON into records in integration tables. For example, it can read the Modbus protocol, gather Modbus data from device registers, convert Modbus binary data into JSON, and store the resulting JSON in integration tables. Once data is in JSON, FairCom Edge can use output protocols to deliver it to other systems, such as Thingworx, SQL, and MQTT.
Some products, such as FairCom Edge can automatically translate across incompatible protocols, such as from MQTT to SQL, MQTT to REST, SQL to REST, Modbus to REST, OPC UA to JSON, etc.
Protocols are incompatible when they communicate in fundamentally different ways. For example MQTT pushes messages, REST requests current information, SQL queries sets of data, OPC UA and Modbus poll devices for telemetry.
FairCom Edgecan translate across incompatible protocols because of the way it uses its high-speed, embedded database to bridge to push, pull, and query protocols.
Modbus is a binary server/client communication protocol developed and published by Modicon for transmitting data to and from electronic devices over a serial bus or TCP/IP network.

MQTT 5 is one of the four MQTT Protocols. As of 2022, it is the most advanced MQTT protocol available to MQTT clients and MQTT brokers. MQTT 5 is supported by many MQTT Clients and MQTT brokers.
It provides advanced features, such as a shared message subscription, which is useful for distributing messages across subscribers for parallel processing. For example, an MQTT broker takes each message published to a shared topic and sends it to a different subscriber. In contrast, a normal subscription receives all messages published to a topic.

Random Access Memory (RAM) is fast, volatile storage that a computer uses to store data. Data in volatile storage is lost when a computer loses power or is turned off. Thus, computers write important information, such as database records to nonvolatile storage, such as file on a durable storage system.
FairCom products and APIs are designed to bridge the gap between volatile and nonvolatile storage. The FairCom uses the Record Buffer Method, which is the fastest technique to move data from a durable storage system into RAM and back. The FairCom JSON DB API is the easiest and most flexible way to move data from a durable storage system into RAM and back. The FairCom is the most traditional way. All these APIs provide transactional durability guarantees, automatic caching, and data replication across storage systems.
The Record Buffer Method is a technique for an application (typically C or C++) to retrieve a record from a file on disk and load it into an application's record buffer for reading and editing. When an application has finished editing the buffer, it writes the buffer back to disk. Because an application allocates a buffer in RAM, the Record Buffer Method is the fastest way to map data on disk to data in an application.
An application typically uses an API, such as FairCom's ISAM or CTDB API, to manage the process of reading and writing records to disk. A mature API can batch process multiple records at a time using arrays of buffers. The Record Buffer Method is exceptionally fast, efficient, and provides predictable performance because it transfers data directly from RAM to disk and vice versa.
The JSON DB API uses JSON over HTTP to manage databases, tables, indexes, records, queries, cursors, and transactions. It is available in all FairCom products.
This API is part of FairCom's family of JSON APIs.
REAL is a FairCom database field type containing a signed floating point number, such as -34028234.664 or 1.1754943508e-38. It is stored in a record as a 4-byte, IEEE 754 , binary floating point number. It provides 6 to 9 decimal digits of approximate precision. In contrast, DOUBLE provides 15 to 19 digits of approximate precision. REAL also supports infinity, -infinity, and NaN.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
DOUBLE is a FairCom database field type containing a signed floating point number, such as -179769313.48623158 or 2.2250738585072014e-308. It is stored in a record as an 8-byte, IEEE 754 , binary floating point number. It supports a wide range of numbers and its calculations are fast. It provides 15 to 19 digits of approximate precision. It supports infinity, -infinity, and NaN.

A database table defines a specific type of record, such as a person's data. A table contains zero or more records. A record contains two or more fields.
In the JSON DB API, a table must always have an "id" field to uniquely identify each record. A table is similar to a collection in a NoSQL database.
A FairCom table may have up to 2500 fields and zero or more of those fields may have a JSON type. Each field (or group of fields) may be indexed by one or more indexes with a maximum of 500 indexed fields. One or more individual properties inside a JSON field may also be indexed.
Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
FairCom's SQL engine is ANSI compliant and has almost all SQL features up through the SQL:2003 standard.
Indexed Sequential Access Method (ISAM) is FairCom's primary ACE API. ISAM uses the Record Buffer Method, which gives the application full control over the contents of the entire record buffer to store structured or unstructured data.
FairCom's ISAM API provides full control over record processing. This allows developers to implement data processing algorithms that are tailored to precise application needs, and this allows an application to achieve unrivaled performance. FairCom's ISAM API works best in the C and C++ languages.

The Low-level ACE API is FairCom's lowest level API. It provides total control over every detail of index and table creation and management. It requires the most code and provides maximum control for maximum server-side performance. It works best in the C and C++ languages.
FairCom ACE APIs include ISAM, CTDB, and Low-level ACE API.

Reformatting transform is one of the primary forms of Data Transforms that changes how the data is stored as bit and bytes — for example, reformatting a binary BSON document to a textual JSON document.
Other types of transforms include reshaping transform and enriching transform.
Reshaping transform is one of the primary forms of Data Transforms that changes how the data is organized — for example, converting deeply nested data in an object into a flat set of properties in a record.
Other types of transforms include reformatting transform and enriching transform.
An enriching transform is one of the primary forms of transforms. It combines data from multiples sources to create more valuable data — for example, looking up data in a database to add new properties to a JSON document or running a machine learning algorithm on the data in a JSON document to classify it and storing the results in the document.
Other types of transforms include reformatting transform and reshaping transform.
In a request-response protocol, a client sends a request to a server and receives a response. This simple technique is the most common form of client-server communications. Because a server cannot push requests to a client, the client is protected from external push attacks.

Representational State Transfer (REST ) is a computer communication protocol that runs actions on a remote computer. It requires HTTP to send requests and receive responses. REST spreads request and response information across a URL, query string, HTTP header, HTTP verb, and HTTP payload.
In contrast, the jsonAction protocol is simpler and easier to use because it encapsulates all information in JSON, and it works over any communication protocol.
Hypertext Transfer Protocol (HTTP) is a standard request-response protocol that works on top of TCP/IP. It allows a client computer to send a request to a server computer, which in turn, replies to the request. The purpose of HTTP is to allow software to ask questions and receive answers.
The JSON Action Protocol (jsonAction) is like REST, jsonAction is a standard way of using JSON to execute actions on remote computers by sending a JSON Action request to a server and receiving back a JSON response. All information needed in a request and its response is included in the JSON. This allows jsonAction to work over any protocol including HTTP, HTTPS, WS, WSS, MQTT, MQTTS, etc.
jsonAction improves on REST by putting all request information in JSON. In contrast, REST spreads request information across a URL, query string, HTTP header, HTTP verb, and HTTP payload. Similarly, jsonAction puts all response information in JSON, whereas REST spreads response information across the HTTP header and HTTP payload. Lastly, REST only works over HTTP whereas, jsonAction works over any protocol including asynchronous protocols.

A server certificate is a certificate that a server computer uses to identify itself to client computers.
A digital identity certificate is an electronic document used by TLS to allow an application, such as a web browser, MQTT client, or server, to know when it is communicating with an intended computer rather than a fraudulent computer impersonating the intended computer.
A service is a capability provided by the server. A FairCom server has many built-in services, including the ability to listen, process, and respond to SQL statements over a TCP/IP port, and the ability to respond to JSON action commands over HTTP and WS. FairCom Edge provides additional services. A service can implement a protocol, such as MQTT, OPC UA, Modbus, and ThingWorx. A service can implement data transformations, such as converting binary data into JSON. Additional services can be added through plugins.

A plugin is a library that a server loads dynamically to provide one or more services. A plugin adds capabilities to the server.
FairCom Edge comes with multiple plugins. One plugin collects OPC UA data, another collects Modbus data, another transforms Siemens UDT into JSON, another sends data to ThingWorx, and so forth. Customers can also create plugins. FairCom plugins have a standard interface that is implemented in C or C++ and compiled as a Windows DLL, a linux SO, or a MacOS dylib.
A FairCom server can be configured to load multiple instances of a plugin library and configure each instance separately, such as configuring it to use different ports and different settings. Therefore, a plugin can be loaded multiple times to provide its set of services multiple times. This is useful to scale the throughput of a plugin or to specify the settings of each plugin instance to provide specialized services. Additionally, a single plugin may implement multiple services.
Shared memory allows applications running on the same computer to communicate with each other using a shared name, such as FAIRCOMS, to identify the shared memory. Each computer operating system defines proprietary APIs for this purpose.
SMALLINT is a FairCom database field type containing a signed integer number, such as -32768. It is stored in a record as a signed 16-bit integer number with a range from -32,768 to 32,767.
Sparkplug B is a specification for MQTT that defines how data is sent and received. Devices and sensors at the edge of a network can use Sparkplug B to communicate with applications like historians and analytics programs. All of this communication goes through an MQTT broker.
Edge is also known as Edge of the Network. The edge is the furthest point in a network, such as smart phones, IoT sensors, smart appliances, factory equipment, vehicles, cloud gateway services, etc. The edge can be mobile, such as a vehicle, or it can be a fixed location, such as a factory, hospital, office, store, building, data center, etc. In simple terms, the edge is any location that is not in the Cloud.
Structured Query Language (SQL) is a standardized programming language that is used to manage relational databases and perform various operations on the data in them.
FairCom's SQL engine is ANSI compliant and has almost all SQL features up through the SQL:2003 standard.
A SQL schema is an owner namespace in a database. A SQL server automatically assigns each user their own schema in each database, which is named after the user's username. A schema automatically contains all database objects created by its user. Thus, a schema is a container for all objects owned by a user. A schema identifies the creator and owner of its objects, which is important because object owners have full control over their objects. A schema is also a namespace for its objects, which allows different users to use the same name for the objects they create.
In FairCom's JSON DB API, the "ownerName" property is used to specify the SQL schema.
SQL schema is not to be confused with JSON schema.
The JSON DB API uses JSON over HTTP to manage databases, tables, indexes, records, queries, cursors, and transactions. It is available in all FairCom products.
This API is part of FairCom's family of JSON APIs.
A database table defines a specific type of record, such as a person's data. A table contains zero or more records. A record contains two or more fields.
In the JSON DB API, a table must always have an "id" field to uniquely identify each record. A table is similar to a collection in a NoSQL database.
A FairCom table may have up to 2500 fields and zero or more of those fields may have a JSON type. Each field (or group of fields) may be indexed by one or more indexes with a maximum of 500 indexed fields. One or more individual properties inside a JSON field may also be indexed.
A record contains data about one thing. A record describes the attributes of a thing using one or more fields. Zero or more records exist in a table; thus, a table contains data about zero or more things.
Different systems represent records differently. A JSON database represents each record as a JSON document. SQL represents each record as a row containing one or more columns of data. ISAM represents each record as a binary buffer of raw bytes.
FairCom products are unique because the FairCom database engine simultaneously supports these different record formats. The same record can be updated and queried simultaneously as JSON, a SQL row, or a binary buffer using the JSON DB API.
The JSON DB API uses JSON over HTTP to manage databases, tables, indexes, records, queries, cursors, and transactions. It is available in all FairCom products.
This API is part of FairCom's family of JSON APIs.

Transmission Control Protocol (TCP) is a standard networking protocol that allows computers to communication, see RFC 793.
Internet Protocol (IP) is the official Internet addressing scheme for uniquely identifies computers in network communications, see RFC 792. IP makes it possible to create networks of networks of computers.
A hostname uniquely identifies a computer on a TCPIP network.
Each computer in a TCP/IP network usually has a hostname assigned to it by a DNS server. When software tries to open a URL, it connects to a DNS server, retrieves the actual IP Address and uses it to connect to the computer.
Hypertext Transfer Protocol (HTTP) is a standard request-response protocol that works on top of TCP/IP. It allows a client computer to send a request to a server computer, which in turn, replies to the request. The purpose of HTTP is to allow software to ask questions and receive answers.
Secure Hypertext Transfer Protocol (HTTP) is the HTTP protocol running over TLS. It provides secure request-response communications between computers.
Internet Protocol (IP) is the official Internet addressing scheme for uniquely identifies computers in network communications, see RFC 792. IP makes it possible to create networks of networks of computers.

Message Queueing Telemetry Transport (MQTT) is the Internet standard protocol for publishing and subscribing to messages that are sent to topics on an MQTT broker (see MQTT.org for more information).
Related terms: MQTT, MQTT 3, MQTT 3.1, MQTT 3.1.1, MQTT 5, MQTT protocol, MQTTS, MQTTWSS, MQTT-SN
Secure Message Queueing Telemetry Transport (MQTTS) is the MQTT protocol running over TLS. It provides secure messaging between computers.
Message Queueing Telemetry Transport over WebSocket Secure (MQTTWSS) is the MQTT protocol running over TLS and WebSocket. It provides secure messaging between computers. It is typically used by single-page browser applications.
A protocol is a defined set of rules for communicating between systems. There are hundreds of communication protocols used by IT, OT, IoT, and IIoT systems. A major cost of integrating systems is writing software or buying hardware to perform the translations required to communicate between systems.
An Integration Hub, such as FairCom Edge, is designed to reduce integration costs by providing built-in translations between protocols. Communication protocols can be categorized as a push protocol, pull protocol, or query protocol. Push, pull, and query protocols are traditionally incompatible with each other, but an Integration Hub, such as FairCom Edge, is designed to automatically bridge across all types of protocols.

Transport Layer Security (TLS) is a secure way for computers to communicate. It uses encryption, a certificate file , and a private key file to create secure communications between computers. TLS was formerly called Secure Sockets Layer (SSL). FairCom products support TLS 1.3, which is the latest version.
WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.

TLS was formerly called Secure Sockets Layer (SSL). FairCom products support TLS 1.3, which is the latest version.
A certificate file contains the certficate required by TLS to prove the identity of a computer.
A private key file is a file that contains the private key required by TLS to prove the identity of a computer. The private key file contains the private key of the public-private key pair that is used to create a computer's digital identity certificate . The private key file typically has the extension, .key, such as server.key or client.pem.
A certificate authority (CA) issues digital identity certificates to identify computers to each other using the TLS protocol. Popular CAs include letsencrypt.org and verisign.com.
A CA certificate is a digital identity certificate issued by a public or private certificate authority (CA).
A digital identity certificate is an electronic document used by TLS to allow an application, such as a web browser, MQTT client, or server, to know when it is communicating with an intended computer rather than a fraudulent computer impersonating the intended computer.
A certificate file contains the certficate required by TLS to prove the identity of a computer.
A client certificate is a digital identity certificate that a client computer uses to identify itself to a server computer.
A certificate signing request (CSR) is a file that contains the identity information needed to create a certificate. A CA creates a certificate by signing a CSR file using its own closely held private key.
A private key is the secret required by TLS to prove the identity of a computer. It is the private key of the public-private key pair that is used to create a computer's digital identity certificate. It is stored in a private key file.
A private key file is a file that contains the private key required by TLS to prove the identity of a computer. The private key file contains the private key of the public-private key pair that is used to create a computer's digital identity certificate . The private key file typically has the extension, .key, such as server.key or client.pem.
A public-private key pair is a pair of asymmetrical keys. The private key can encrypt a secret and only the public key can decrypt that secret. This also works in reverse where the public key can encrypt a secret and only the private key can decrypt that secret.
A server certificate is a certificate that a server computer uses to identify itself to client computers.
TLS handshake is a series of requests by a client computer and the corresponding responses by a server computer.
TLS handshake is a series of requests by a client computer and the corresponding responses by a server computer.
A data transformation converts one form of data into another. The primary forms of data transformations include enriching transforms, reformatting transforms, and reshaping transforms. A transform may combine any or all types of transformations.
A transform in FairCom Edge is a process that uses one or more transform services to transform data in an integration table. Each integration table has a configurable transform process that runs each time a record is inserted into that table. The transform process may contain zero or more transform steps. Each step runs a transform method supplied by a transform service. Each step can send its output as the input of a subsequent transform step.
By chaining together transform services FairCom Edge can convert the initial data into one or more output formats, shapes, enrichments, and generated results. So when a record is inserted into an integration table, the table's transform process can take the contents of the "source_payload" field and update the transforms fields "t1" through "t9" with a wide variety of transformed results, such as JSON documents, XML documents, binary data formats, modified or generated images, metadata, results of machine learning, and so forth. Output services can use any of these fields as their source of data making it easy for data to come into FairCom Edge in one format and go out to many different services in different formats.
FairCom Edge ships with several transform plugins that provide a variety of transform services, such as converting Siemen’s native binary PLC data into JSON, converting JSON into tables, converting tables into JSON, transforming the structure of JSON documents, transforming the values of JSON properties, and more.
An enriching transform is one of the primary forms of transforms. It combines data from multiples sources to create more valuable data — for example, looking up data in a database to add new properties to a JSON document or running a machine learning algorithm on the data in a JSON document to classify it and storing the results in the document.
Other types of transforms include reformatting transform and reshaping transform.
Reformatting transform is one of the primary forms of Data Transforms that changes how the data is stored as bit and bytes — for example, reformatting a binary BSON document to a textual JSON document.
Other types of transforms include reshaping transform and enriching transform.
Reshaping transform is one of the primary forms of Data Transforms that changes how the data is organized — for example, converting deeply nested data in an object into a flat set of properties in a record.
Other types of transforms include reformatting transform and enriching transform.
An integration table is an enhanced database table used by FairCom Edge and FairCom MQ. It is enhanced to do the following things automatically: collect data from input connectors, add time series data, transform data, and push data to output services with guaranteed delivery.
A type is the data type of a field in a table. In a FairCom server, data is stored in fields, records, tables, and databases. A record contains one or more fields. A table contains zero or more records. Each field has a predefined field type.
A FairCom server provides strongly typed fields and flexibly typed fields, which can be freely mixed into any table. Strongly typed fields make queries predictable and fast.
The most common strongly typed fields are NUMERIC, INTEGER, VARCHAR, LVARBINARY, BIT, DATE, TIME, and TIMESTAMP. The remaining strongly typed fields have specialty purposes.
A FairCom server also supports JSON fields, which may flexibly contain any JSON type.
A FairCom table may have up to 2500 fields and zero or more of those fields may have a JSON type. Each field (or group of fields) may be indexed by one or more indexes with a maximum of 500 indexed fields. One or more individual properties inside a JSON field may also be indexed.

JSON consists of one or more JSON values that can be nested inside each other.
Each value is one of the data types: JSON object, JSON array, JSON string, JSON number, JSON Boolean, or JSON null.
Related terms: JSON, JSON data type, JSON value, JSON array, JSON object, JSON property, JSON number, JSON string, JSON Boolean, JSON null
User Defined Type (UDT) is a user-defined data structure in a programming language, such as C, C++, Java, etc.
FairCom Edge provides an advanced transform that can take native binary user-defined types in a Siemens PLC and convert them into JSON.
Uniform Resource Locator (URL) is a standard way for uniquely addressing resources on a network. A URL is an Internet standard that uses the following pattern: protocol://domainName:portNumber/resource.
Common FairCom URLs include https://docs.faircom.com/docs/ and https://localhost:8443/.
This URL launches a menu for running the FairCom browser-based applications. It works when a Google Chrome web browser runs on the same computer where the FairCom server is running.
Google Chrome may complain that your connection is not private. To resolve this issue see Solve certificate security problems in Google Chrome. FairCom browser-based applications are safe and become more secure when you replace FairCom's default certificate with your own security certificate.
If https://localhost:8443/ does not work, try https://127.0.0.1:8443/ . Also make sure the FairCom server is running.
When running the Google Chrome web browser and the FairCom server on different computers, change localhost to the hostname or IP Address of the server where the FairCom server is running.
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude. It is a successor to Greenwich Mean Time (GMT) or ZULU time. It has a timezone offset of 0, and it is not adjusted for daylight saving time.
VARBINARY is a FairCom database field type containing a variable-length binary value. It is stored in a record as a variable-length sequence of bytes with a user-defined maximum length up to 65,500 bytes.
VARCHAR is a FairCom database field type containing a variable-length string, such as "my string". It is stored in a record as a variable-length sequence of UTF-8 characters with user-specified maximum length up to 65,500 bytes.
WebSocket is a standard communication protocol for bidirectional exchange of data between computers, see RFC 6455. It works over TCP/IP and HTTP. It is often used by single page web applications because web browsers have built in support for WebSocket. It is also used by applications and servers that want to push messages to other computers in additional to using the request-response provided by HTTP.
In a request-response protocol, a client sends a request to a server and receives a response. This simple technique is the most common form of client-server communications. Because a server cannot push requests to a client, the client is protected from external push attacks.
The jsonAction protocol is a request-response protocol.
