hi all,
->designpattern means it is the solution for the
reoccuring problem.
->The main aim of the MVC architecture is to separate
the business logic and application data from the
presentation data to the user.
->in model we can write our own code(like beans).
simply we can say that model is responsible for
managing the data.
->in view component we can write jsp code.
->controler is responsible for controling the application.
as part of controler we can write the servlet code.
use of mvc:-
1)suppose we write the code as part of controler to connect
to oracle database.
now i want to connect to another database like sybase.in
that particular swictuation i dont need to change model and
view components.what ever the code up to that controler
part only has been changed.
so that performance of the application automatically
increased.
there is the clean separation between the business logic
and presentation logic.
2) By using the MVC design pattern our
application becomes more expressive
