Model-View-Controller and Model-View-Presenter Patterns Quick Comparison | MVC and MVP Short Explanation

The Model-View-Controller (MVC) and Model-View-Presenter (MVP) Patterns improve reusability of business logic by separating the three components required to generate and manage a specific user interface (such as a single Web page). The Model contains the data that the View (the Web page) will display and allow the user to manipulate. The Controller or Presenter links the Model and the View, and manages all interaction and processing of the data in the Model (see Figure 1).

In the MVC pattern, user interaction with the View raises events in the Controller, which updates the Model. The Model then raises events to update the View. However, this introduces a dependency between the Model and the View. To avoid this, the MVP pattern uses a Presenter that both updates the Model and receives update events from it, using these updates to update the View. The MVP pattern improves testability, as all the logic and processing occurs within the Presenter, but it does add some complexity to the implementation because updates must pass from the Presenter to the View.
