20. Django Architecture
Django follows MVT pattern. MVT is a software design pattern. It is a collection of
three important components Model View and Template.
Model: The Model helps to handle database. It is the backend where your
database is defined.
Template: The Template handles User Interface part completely
View: The View is used to execute the business logic and interact with a model to
carry data and renders a template.A user sends the request via the browser.
Django works as a controller and checks to the available resource in URL. If URL
maps, a view is called.The view interacts with model and template, retrieves data
from the database via the model, formats it, render a template as a response.
