8. The MVC Architecture
• MVC (an architectural paradigm) is a standard and
extremely popular design pattern, based on concepts
developed back in 1979.
•Structure of your web development and your
programming is going to be built in a certain way in
this MVC format where we are going to separate our
Model, View and Controller.
•Just a way of thinking and structuring your web
applications.

9. Why so popular?
• Used by many popular frameworks
– Ruby on rails (First one to use it).
– Django (Python based web framework).
– Cake PHP.

JavaScript.

14. Controller
• Processes GET/POST/PUT requests.
• The server side logic.
• The Middle Man:
– Takes info from the user.
– Processes info and talks to the database if needed.
– Receives info from DB.
– Speaks to View to explain presentation to the
viewer.

15. The Controller

16. Advantages of an MVC-Based Web
Application
• It makes it easier to manage complexity by dividing an
application into the model, the view, and the controller.
• It provides better support for test-driven development
(TDD).
• Helps in carrying out the development in a more secure
manner.
• It works well for Web applications that are supported by
large teams of developers and for Web designers who need a
high degree of control over the application behaviour.

17. Example
• A basic application which stores student
information and retrieves it.
