Django ORM

Django ORM (Object-Relational Mapping) is a powerful feature of the Django web framework that allows developers to interact with relational databases using Python code instead of SQL. It provides a high-level abstraction for database operations, enabling you to create, retrieve, update, and delete records in a database without writing raw SQL queries. This not only speeds up development but also reduces the likelihood of errors.

Django ORM supports various relational databases, including SQLite, PostgreSQL, and MySQL. It automates the translation of Python code into SQL, making it easier for developers to work with databases. The ORM also includes features like QuerySets, which allow for complex queries and data manipulation, and optimizations such as prefetch_related and select_related to improve performance ¹³.

For those looking to deepen their understanding, there are numerous resources available, including tutorials, examples, and practice problems that can help you become proficient in using Django ORM ⁵.
