Have fun with MDA: modeling business logic

This is part three of my five-part tutorial that shows how to implement a web-based database application with a powerful MDA-Tool called OlivaNova Modeler. In this part, I'll explain how to implement nearly any business logic within the software model. When generating the code, the business logic is also transformed into C# code that matches the business logic defined in the model - and of course - you could also transform it into Java J2EE code that behaves identically.
