Easy Framework implements the Model-View-Controller (MVC) design pattern, and encourages application design based on this paradigm. MVC allows the Web page (i.e. View) to be mostly separated from the internal application code (Controller/Model), making it easier for designers and programmers to maintain and organise their code.
The Model contains the business logic for the application, whereas the Controller forwards the request to the appropriate View component. The view itself should not contain any further logic (apart from some design topics) or even database requests.
Easy Framework is not a port of Jakarta Struts or anything else. It doesn't try to mimic anything (of the Java world), but is a collection of "best-practice" experience.
