FairCom Java Stored Procedures

Transaction Processing

Now we will discuss transaction processing as it relates to the FairCom DB SQL Stored Procedures Technology.

Transaction processing provides a safe method by which multiple database operations spread across separate tables/files are guaranteed to be atomic. By atomic, we mean that, within a transaction, either all of the operations succeed or none of the operations succeed. This "either all or none" atomicity ensures that the integrity of the data in related tables/files is secure.

Like all other examples in the c-tree tutorial series, this tutorial simplifies the creation and use of a database into four simple steps: Initialize(), Define(), Manage(), and You’re Done()!

Tutorial #4: Transaction Processing

Here we demonstrate transaction control.

Initialize() - Connects to the FairCom Database Engine.
Define() - Defines and creates our four tables/files.
Manage() - Adds rows/records to multiple tables/files under transaction control.
Done() - Disconnects from FairCom Database Engine.

Note these sections in our SQL Script:

-- Initialize

ECHO INIT;

-- Define

ECHO DEFINE;

-- Manage

ECHO MANAGE;

-- Done

ECHO DONE;

We suggest opening the source code with your own editor.

Continue now to review these four steps.
