What is a Model View Controller (MVC) Framework?
MVC is a framework methodology that divides an application's implementation into three component roles: models, views, and controllers.

  • "Models" in a MVC based application are the components of the application that are responsible for maintaining state.  Often this state is persisted inside a database (for example: we might have a Product class that is used to represent order data from the Products table inside SQL).
  • "Views" in a MVC based application are the components responsible for displaying the application's user interface.  Typically this UI is created off of the model data (for example: we might create an Product "Edit" view that surfaces textboxes, dropdowns and checkboxes based on the current state of a Product object).
  • "Controllers" in a MVC based application are the components responsible for handling end user interaction, manipulating the model, and ultimately choosing a view to render to display UI.  In a MVC application the view is only about displaying information - it is the controller that handles and responds to user input and interaction.

One of the benefits of using a MVC methodology is that it helps enforce a clean separation of concerns between the models, views and controllers within an application.  Maintaining a clean separation of concerns makes the testing of applications much easier, since the contract between different application components are more clearly defined and articulated.
