What is Django's ORM and how does it work?

Django's Object-Relational Mapping (ORM) is a powerful tool that allows developers to interact with a database using Python objects. It abstracts the database schema and operations, making it easier for developers to work with databases without writing complex SQL queries.

The ORM works by mapping Python classes to database tables, and Python objects to rows in those tables. This allows developers to manipulate database records using Python code, rather than directly dealing with SQL queries.

One key benefit of Django's ORM is that it allows for database independence, meaning developers can easily switch between different database backends without changing their code significantly.
