The Model is made up of business objects and data Each MVC application typically has a user interface that displays information to a user and allows the user to input data The data that the View displays is read from a Model, and the data that the user adds to the View is assigned to the Model A Controller orchestrates the activities of an application When a user makes a request for your application, ASPNET MVC invokes a Controller The Controller will communicate with the Model and View to ensure the program operates correctly
