Model View Presenter (MVP) is a derivative of the model-view-controller software pattern, used mostly for building user interfaces.

Model-view-presenter (MVP) is a derivative of the model-view-controller software pattern, used mostly for building user interfaces.

In MVP, the presenter assumes the functionality of the "middle-man" (played by the application controller in MVC). Additionally, the view is responsible for handling the UI events (like mouse down, key down, etc.), which used to be the controller's job. Eventually, the model becomes strictly a domain model.
