Django ORM (Object-Relational Mapping) is a layer that allows you to interact with databases using Python code instead of SQL. It maps database tables to Python classes and rows to objects.

Advantages:

• Database abstraction: Works with multiple database backends
• Security: Prevents SQL injection attacks
• Portability: Easy to switch between databases
• Pythonic: Write database queries using Python syntax
• Automatic SQL generation: ORM generates optimized SQL queries
• Migrations: Automatic schema management
