MVC is an acronym for Model View Controller which is a well-known design pattern for building applications. You ll learn about how MVC works and how it is implemented in MVC. Let s start by helping you understand what MVC is. Understanding MVC The essential piece of knowledge required to be successful with MVC is the Model View Controller pattern. In MVC the Model View and Controller are three separate objects. Table 9-1 describes the purpose of each MVC object. With MVC you have a clear separation of concerns where Model View and Controller have distinct responsibilities. This makes it easier to write good programs that you can return to later for fixing bugs and adding new features. Besides knowing what each of these three objects is you must understand their relationship. Figure 9-1 illustrates the Model the MVC Object Purpose Model The Model is made up of business objects and data. View 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. Controller A Controller orchestrates the activities of an application. When a user makes a request for your application MVC invokes a Controller. The Controller will communicate with the Model and View to ensure the program operates correctly.
