FairCom ADO.NET Driver - Developer's Guide

Transactions

drivers\csharp.sql.ado.net\tutorials\CSharpTutorial4.cs

Now we will discuss transaction processing as it relates to the FairCom DB ADO.NET Data Provider using C#.

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:

using System;

using System.Collections;

using Ctree.Data.SqlClient;

namespace CSharpTutorial

{

class Tutorial4

{

// declare connection, command and reader objects

static CtreeSqlConnection conn;

static CtreeSqlCommand cmd;

static CtreeSqlDataReader rdr;

//

// main()

//

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

// and you're done..."

//

static void Main()

{

Initialize();

Define();

Manage();

Done();

Console.Write("\nPress <ENTER> key to exit . . .");

Console.ReadLine();

}

We suggest opening the source code with your own editor.

Continue now to review these four steps.
