The main aim of the MVC architecture is to separate the
business logic and application data from the presentation
data to the user.
Here are the reasons why we should use the MVC design pattern.
1. They are resuable : When the problems recurs, there is
no need to invent a new solution, we just have to follow the
pattern and adapt it as necessary.
2. They are expressive: By using the MVC design pattern
our application becomes more expressive.
1). Model: The model object knows about all the data that
need to be displayed. It is model who is aware about all the
operations that can be applied to transform that object. It
only represents the data of an application. The model
represents enterprise data and the business rules that
govern access to and updates of this data. Model is not
aware about the presentation data and how that data will be
displayed to the browser.
2). View : The view represents the presentation of the
application. The view object refers to the model. It uses
the query methods of the model to obtain the contents and
renders it. The view is not dependent on the application
logic. It remains same if there is any modification in the
business logic. In other words, we can say that it is the
responsibility of the of the view's to maintain the
consistency in its presentation when the model changes.
3). Controller: Whenever the user sends a request for
something then it always go through the controller. The
controller is responsible for intercepting the requests from
view and passes it to the model for the appropriate action.
After the action has been taken on the data, the controller
is responsible for directing the appropriate view to the
user. In GUIs, the views and the controllers often work
very closely together.
