Django Architecture: MVC and MVT
MVC Pattern:
When talking about applications which provide UI (web or desktop), we usually talk about MVC architecture. MVC pattern is based on Model, View, and Controller.
The Model defines the data structure and takes to care for querying the database.
The View defines what data should be presented and returns an HTTP response.
The Controller is that part of the application that handles the user interaction.

Django MVC-MVT pattern
The Model-View-Template (MVT) is a different concept compared to MVC.
The main difference between these two architectural patterns is that Django itself manages the Controller part (software code that controls the interactions between the Model and View).
The template is an HTML file which mixed with Django Template Language file which also called DTL.
The below-given diagram shows how all the components of the MVT pattern interact with each other to serve specific to a user request.
