What is Django

The Django framework implements the Model-View-Template architectural pattern,
or MVT for short, which is actually a modification of the MVC (Model-View-Controller) pattern common in web programming.

The main elements of the pattern:

URL dispatcher: When a request is received, based on the requested URL,
determines which resource should handle this request.
View: receives a request, processes it, and sends some response back to the user.
If processing a request requires access to the model and database, then the View interacts with them.
Can use Template or templates to create a response.
In the MVC architecture, controllers (but not views) correspond to this component.\
Model: describes the data used in the application.
Individual classes generally correspond to tables in a database.\
Template: Represents the presentation logic as generated html markup.
In MVC, this component corresponds to View, that is, views.
