This tutorial will take you through the basic use of the FairCom DB CodeGear VCL ISAM Component Framework - Delphi.

As with 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 #1: Introductory - Simple Single Table

We wanted to keep this program as simple as possible. This program does the following:

Initialize() - Connects to the FairCom Database Engine.
Define() - Defines and creates a "customer master" (custmast) table/file.
Manage() - Adds a few rows/records; Reads the rows/records back from the database; displays the column/field content; and then deletes the rows/records.
Done() - Disconnects from FairCom Database Engine.

Note our simple Main() function:

procedure TForm1.btnStartClick(Sender: TObject);

begin

Init;

Define;

Manage;

end;

procedure TForm1.btnDoneClick(Sender: TObject);

begin

Done;

Close;

end;
