The MVC (Model View Controller)

The MVC (Model View Controller)

introduction to MVC concepts as they are implemented in CakePHP.MVC (Model View Controller)

framework that inspired CakePHP: Ruby on Rails. Ruby on Rails is a web framework for the

programming language Ruby. It implements both Active Record and MVC.

The MVC paradigm is a way of breaking an application, or even just a piece of an

application's interface, into three parts: the model, the view, and the controller. MVC was

originally developed to map the traditional input, processing, output roles into the GUI

Input -> Processing -> Output

Controller -> Model -> View


The user input, the modeling of the external world, and the visual feedback to the user are separated and handled by model, view port and controller objects. The controller interprets mouse and keyboard inputs from the user and maps these user actions into commands that are sent to the model and/or view port to effect the appropriate change. The model manages one or more data elements, responds to queries about its state, and responds to instructions to change state. The view port manages a rectangular area of the display and is responsible for presenting data to the user through a combination of graphics and text.
