MVC

MVC = Model-View-Controller
 Clearly separates business, navigation and presentation logic.

• Controller :- Handles navigation logic and interacts with the service tier for business logic.
• Models :- Models represent knowledge. A model could be a single object (rather uninteresting), or it could be some structure of objects.
• View :- A view is a (visual) representation of its model. It would ordinarily highlight certain attributes of the model and suppress others. It is thus acting as a presentation filter.
