The Joomla MVC Design Pattern

Model-View-Controller (MVC) is a set of design patterns, that are used to separate the different layers of your application.

• The View displays the data of the model by passing it to a template. The view object can therefore access the data of the model. Joomla implements the basic functionality in the abstract JView class.
• The Model stores the data of the application, and contains the business logic. Joomla implements the basic functionality in the abstract JModel class.
• The Controller handles the user requests and evokes the model and the views to change it's state. Joomla implements the basic functionality in the JController class.
