Factory-Worker Objects
So what, really, is a business object and how is it implemented? Well, in the Visual Basic world, a business object is a public object that exposes business-specific attributes. The approach TMS takes toward business objects is to employ the action-factory-worker model. We'll come to the action objects later, but for now we'll concentrate on the factory-worker objects.
A quick note about terminology: in this design pattern there is no such thing as an atomic "business object" itself. The combination of the interaction between action, worker, and factory can be described as a logical business object.
