This sample is an introduction to Rockford Lhotka's Component-based Scalable Logical Architecture (CSLA) as described in his book, "Visual Basic 6 Business Objects" (Wrox Press, 1998). .Net concepts demonstrated include C#, Windows Forms, Custom Events, Database Access (ADO.NET).

An abstract factory provides an interface for creating families of related objects without specifying their concrete classes. Sometimes one wants to construct an instance of one of a suite of classes, deciding between the classes at the time of instantiation. In order to avoid duplicating the decision making everywhere an instance is created, we need a mechanism for creating instances of related classes without necessarily knowing which will be instantiated.

The Builder pattern allows a client object to construct a complex object by specifying only its type and content. The client is shielded from the details of the objects construction. This article includes example implementations in C# and Visual Basic .NET.
