What is the role of the model in the architecture of a Django application?

In a Django application architecture, the model is responsible for representing data and the business logic associated with it. It defines the structure of database tables through classes that inherit from django.db.models.Model.

Model:

• Defines fields and their types (e.g., CharField, IntegerField).
• Contains methods for working with data (e.g., computed properties).
• Responsible for data validation.

Example model:

from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)

    def __str__(self):
        return self.name

Thus, the model acts as a link between the database and the rest of the application, providing convenient and secure access to data.
