These tutorials introduce you to the most basic Direct SQL API functions, to create and manipulate a table through the ctreeServer.
As with all other tutorials in the c-tree series, each of these database programming tutorials is implemented with four simple code procedures: Initialize(), Define(), Manage(), and Done().
No matter which FairCom interface language you use, FairCom follows this same high-level flow in all tutorials. This makes it easy for developers to "cross-over" from one language interface to another as these basic concepts apply to all.
|
Initialize() Every language requires some form of initial "logon" or "connection" procedure to establish a session with the database. This is done in the Initialize() stage of the program. |
|
Define() Database definitions (DDL), Table/File schema definitions, Index definitions, Table/File creation, and Table/File open operations are all addressed in the Define() stage of the program. |
|
Manage() This stage of the program is where the database is operated on, as in managing your data. Adding/Reading/Updating/Deleting records/rows are handled in this stage of the program. |
|
Done() When the program ends, the database session should be closed. This stage handles the necessities to "de-init", by closing Tables/Files and issuing any required "logoff" or "disconnect" type procedures. |
Presented here are tutorials that follow the "Initialize(), Define(), Manage(), and Done()" approach.
