INTRODUCTION
Django uses the Model-View-Controller (MVC) pattern, with slight variations,
primarily following the Model-Template-View (MTV) pattern. This structure
enhances developer productivity and maintainability. Models represent the
data layer, View handles presentation logic, and Controller coordinates
interactions. MTV maintains data-related tasks, while Views serve as
Controllers, promoting maintainable code and modularity in Django web
applications. the data layer, View handles presentation logic, and Controller
coordinates interactions. MTV maintains data-related tasks, while Views
serve as Controllers, promoting maintainable code and modularity in Django
web applications.

DJANGO ARCHITECTURE
COMPONENTS
• Django's Model is the data layer, encapsulating application
structure, ensuring integrity, and handling database interaction,
defined as Python classes inheriting from
django.db.models.Model.
• Django's Views are Python functions that handle incoming
requests, data retrieval, and rendering, encapsulating application
logic and handling business logic, determining data display and
user response.
• Django templates, like the View component in MVC, generate the
application's presentation layer, containing HTML markup,
embedded tags, and filters, dynamically rendering data and
sending output to the client's web browser.

Simplified example of a
Django model
from django.db import models
class Post(models.Model):
title =models.CharField(max_length=100)
content = models.TextField()
created_at =
models.DateTimeField(auto_now_add=True)

Example of a Django View
Function: from django.http
import HttpResponse def hello(request):
return HttpResponse("Hello, Django!")
from django.shortcuts import render
from .models import Product

Example of a Django
Template:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, initial-
scale=1.0">
<title>My Template</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
