MVC is a software design pattern. It describes the separation of software into three elements:
Model : Manages the data of an application. This is to be understood in a narrow sense. Of course, any part of a less than trivial application deals with the application’s data in one way or another, but the model from MVC corresponds to data items viewable to the user and possibly subject to change by user interactions. The model is agnostic to the way the data is represented to the user or any application workflow, so it can be said that the model is the central part of a MVC application. ...
