| − | ===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.
