Model-View-Controller (MVC) is a design pattern put together to help control change. MVC decouples interface from business logic and data.
? Model: The model having the core of the application's functionality. The model encapsulates the state of the application. Sometimes the only functionality it having is state. It knows nothing about the view or controller.
? View: The view gives the presentation of the model. It is the look of the application. The view can access the model getters, but it has no knowledge of the setters. In addition, it knows nothing about the controller. The view should be notified when changes to the model happen.
? Controller: The controller reacts to the user input. It makes and sets the model.
