Data Abstract for Delphi comes with two samples that demonstrate the use of Business Rules Scripting to provide data validation in the middle tier rather than in the client application.
The sample also demonstrates using DA SQL to selectively retrieve some data from the schema, rather than the whole table.
Typically the samples are located in `C:\Program Files (x86)\RemObjects Software\Data Abstract for Delphi\Samples. Inside that folder you will find folders for each programming language that Data Abstract for Delphi supports.
Sample 1: Console based program
The Console Sample is a non interactive program that retrieves data and prints it to the console.
Sample 2: Desktop based program
The Desktop Sample is an interactive program.
