Structured Application Design with MVC MVC defines a clean separation between the critical components of our apps. Consistent with its name, MVC defines three parts of an application: • A model provides the underlying data and methods that offer information to the rest of the application. The model does not define how the application will look or how it will act. • One or more views make up the user interface. A view consists of the different onscreen widgets (buttons, fields, switches, and so forth) that a user can interact with. • A controller is typically paired with a view. The controller is responsible for receiving user input and acting accordingly. Controllers may access and update a view using information from the model and update the model using the results of user interactions in the view. In short, it bridges the MVC components.
