Course Description

This course provides a comprehensive introduction to Django’s Object-Relational Mapping (ORM) system, which allows developers to interact with databases using Python code instead of raw SQL. You will learn how to define models, perform queries, filter data, and manage relationships between tables efficiently using Django's powerful ORM features. The course is designed with practical examples and hands-on exercises to help you build real-world applications with clean and maintainable code.

Understand the fundamentals of Django ORM and how it maps Python classes to database tables.
Create, retrieve, update, and delete data using ORM queries.
Work with model relationships such as one-to-many and many-to-many.
Optimize queries for performance using techniques like select_related and prefetch_related.
Handle data validation, constraints, and custom model methods.
Build a solid foundation for developing full-stack Django applications backed by relational databases.

By the end of this course, you will be able to confidently use Django ORM to manage database operations in your web applications, ensuring cleaner code, better performance, and faster development.
