MVC Definition

MVC is short for Model View Controller and is a three layer pattern for isolating business logic from user interface. The user interacts via a user interface. The controller then handles these inputs and directs them to the model.

Structure:

What is a Controller?

Controllers will be the receivers and dispatchers. When a user sends a request by clicking a link or button then the request is handed over to the controller (There can be many controllers in the website and the correct controller to handle a particular request will be identified by the URL pattern) the controller will have a set of methods (show, index, etc...) defined and one of these methods will do the necessary tasks to generate a response. Basically, Controller will be the intermediary who will communicate with the Modal and generate an appropriate View and send that to the client.

What is a Model?
Model handles the database interactions for the application. The Model will return the data which is requested by the Controller.

What is a View?
View is the HTML output that a user sees when he makes a page request. This view will be rendered based on the Controllers' request and by the data that is passed in by the Model.
