MVC Architecture

MVC stands for Model, View and Controller. MVC separates application into three components - Model, View and Controller.
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.
View: View is a user interface. View display data using model to the user and also enables them to modify the data.
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.
How does MVC works?

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 response and sends it back to the user.
