Pull-MVC vs. Push-MVC based architecture

Pull-MVC and Push-MVC are better understood with how the view layer is getting data i.e. Model to render.

Pull-MVC puts the model data typically constructed in Controllers are kept in a common place i.e. in actions, which then gets rendered by view layer.

Example : Struts 2x

Struts2 is a Pull-MVC based architecture, in which all data is stored in Value Stack and retrieved by view layer for rendering.

In case of Push-MVC, the data (Model) is constructed and given to the view layer by the Controllers by putting it in the scoped variables like request or session.
