Introduction to the ORM

The Django framework includes an Object-Relational Mapper (ORM) layer, which is not specific to Django; you can find it in other programming languages as well. For example, Flask typically utilizes SQLAlchemy, which is another ORM.

The ORM is a powerful feature of Django that allows you to interact with your database. It provides a Pythonic way to create SQL queries and manipulate the database, making developers' lives easier.

The ORM maps the Python objects we create to database objects. In simple terms, it bridges the gap between Python and SQL.

Django's ORM automatically connects your project to the database. It's straightforward to use and follows the Active Record design pattern, where each database table corresponds to a Python class (model).

In conclusion, ORM accelerates application development and allows you to use Python instead of writing raw SQL queries. It also simplifies database migrations when working with different databases.
