Transaction Processing

Now we will discuss transaction processing as it relates to the FairCom DB JDBC Interface.

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 our simple Main() function:

import java.sql.*;

import java.io.*;

public class JDBC_Tutorial4 {

static Connection conn;

static Statement stmt;

//

// main()

//

// The main() function implements the concept of "init, define, manage

// and you're done..."

//

public static void main (String[] args)

throws java.io.IOException

{

Initialize();

Define();

Manage();

Done();

System.out.print("\nPress <ENTER> key to exit . . .");

System.in.read();

System.exit(0);

}

We suggest opening the source code with your own editor.

Continue now to review these four steps.
