A brief comparison of the 12 most popular ORMs
Object-Relational Mapping (ORM) is a technique that helps developers interact with databases by providing a convenient, object-oriented interface.
In recent years, several ORMs have become popular among developers, each offering its own set of features and benefits. Here’s a brief comparison of some of the most popular ORMs and their pros and cons.
Django ORM
Django ORM is a part of the Django web framework and is widely used to build web applications. It provides a high-level, easy-to-use API for interacting with databases and supports a variety of databases including PostgreSQL, MySQL, and SQLite.
One of the biggest advantages of Django ORM is its built-in support for transactions, making it easy to manage complex database operations. However, the high-level nature of the API can make it less flexible compared to other ORMs.
