5.  This model divides the web based application
into three layers:
• Model
• View
• Controller

6. Model:
• Model domain contains the business logics
and functions that manipulate the business
data.
• It provides updated information to view
domain and also gives response to query.
• And the controller can access the
functionality which is encapsulated in the
model.

7. View:
• View is responsible for presentation aspect of
application according to the model data and
also responsible to forward query response
to the controller.

8. Controller:
• Controller accepts and intercepts user
requests and controls the business objects to
fulfill these requests.
• An application has one controller for related
functionality.

clients.
