How is the interaction between Django and the database carried out through ORM?

In Django, interaction with the database is carried out through ORM (Object-Relational Mapping), which allows working with data as Python objects rather than directly through SQL queries.

Main points:

• Django models describe the structure of database tables as classes.
• When performing operations with models (creation, reading, updating, deleting), ORM automatically generates the corresponding SQL queries.
• ORM manages the connection to the database, transactions, and data conversion between Python and SQL.

Example:

from myapp.models import Book

# Creating a record
book = Book(title='Python', author='Author')
book.save()

# Retrieving records
books = Book.objects.filter(author='Author')

Thus, ORM simplifies working with the database, hiding SQL details and allowing for more readable and maintainable code.
