MVC OverView

Introduction

The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller. The ASP.NET MVC framework provides an alternative to the ASP.NET Web Forms pattern for creating Web applications. The ASP.NET MVC framework is a lightweight, highly estable presentation framework that (as with Web Forms-based applications) is integrated with existing ASP.NET features, such as master pages and membership-based authentication. The MVC framework is defined in the System.Web.Mvc assembly.

Model:   
                 Model represents shape of the data and business logic.It maintains the data of The application. Model objects retrieve and store model state in a database.
                                   Note -     Model is a data and business logic.
View:  
              View is a user interface. View display data using model to the user and also enables them to   modify  the data.
                                   Note -  View is a User Interface.

Controller:

                       Controller handles the user request. Typically, user interact with View, which in-tern raises appropriate URL request, this request will be handled by a controller. The controller renders the appropriate view with the model data as a response.

                                 Note -   Controller is a request handler.

MVC Architecture

The following figure illustrates the flow of the user's request in ASP.NET MVC  See Above-.

                                             Request/Response in MVC Architecture                                      

As per the above figure, when the user enters a URL in the browser, it goes to the server and calls appropriate controller. Then, the Controller uses the appropriate View and Model and creates the

the response and sends it back to the user.
