Django ORM Documentation

Django ORM (Object-Relational Mapping) is a powerful tool that allows developers to interact with databases using Python code instead of writing raw SQL queries. It abstracts the database layer, making it easier to work with relational databases like PostgreSQL, MySQL, or SQLite.

Key Features of Django ORM

• Model Definition: Define database models using Python classes.
• Query Handling: Perform database queries using high-level methods.
• Database Agnosticism: Works with multiple databases through backends.
• Relationships: Manage relationships between models (e.g., One-to-One, Many-to-Many).

Example Usage

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey('Author', on_delete=models.CASCADE)
    published_date = models.DateField()

class Author(models.Model):
    name = models.CharField(max_length=50)
    bio = models.TextField()
