The MVC design pattern calls for a separation of code by their function: • Model: Code to control data access and persistence. • View: Code to handle how data is presented to the user. • Controller: Code to handle data flow and transformation between Model and View. Figure 5-1 illustrates MVC.
The idea of the MVC pattern is to separate the following aspects of an applica-tion: the model: capturing the state of an application and its internal logic dictating how its state changes when actions are performed; the controller: capturing how the model is informed of actions that are performed (generally, this is driven by input from the user);
Understanding the MVC Pattern. In high-level terms, the MVC pattern means that an MVC application will be split into at least three pieces. Models, which contain or represent the data that users work with. Views, which are used to render some part of the model as a user interface.
the goal of the MVC pattern is to divide an application into three functional areas, each of which may contain both logic and data. The goal isn t to eliminate logic from the model.
This paper presents an analysis of those changes, and proposes a separate Web-MVC pattern that more accurately describes how MVC is implemented in web frameworks. The MVC is very useful for constructing dynamic software systems.

The Model-View-Controller (MVC) design pattern is cited as the basis for the architecture of several web application frameworks, such as ASP .Net, Rails, and Struts. The MVC pattern was originally implemented in the Smalltalk-80 programming environment developed at Xerox PARC (Goldberg and Robson, 1985).
