Questions : 1 Whatís MVC pattern ?
Answers : 1

The main purpose of using MVC pattern is to decouple the GUI from the Data. It also gives the ability to provide multiple views for the same Data. MVC pattern separates objects into three important sections:-

Model: - This section is specially for maintaining data. It is actually where your business logic, querying database, database connection etc. is actually implemented.
Views: - Displaying all or some portion of data, or probably different view of data. View is responsible for look and feel, Sorting, formatting etc.
Controller: - They are event handling section which affects either the model or the view. Controller responds to the mouse or keyboard input to command model and view to change. Controllers are associated with views. User interaction triggers the events to change the model, which in turn calls some methods of model to update its state to notify other registered views to refresh their display.
