MVC

                                                                        

• Design Pattern that separates an application into three interconnected components
• model (data): Represents the data and business logic.
• view (user interface): Represents the User Interface
• controller (logic): Handles user input and updates the model and view accordingly.
• Flow of data between components is unidirectional.
• Activities
• First user interact with view like by clicking button, a keystroke etc.
• View notifies the controller about this input
• Controller receives the input from the view and decides how to update the model and view accordingly
