SQLAlchemy

SQLAlchemy is a powerful Python library that serves as an object-relational mapper (ORM) and a database toolkit. It allows developers to interact with databases using Python objects instead of writing raw SQL queries. This abstraction simplifies database operations, making it easier to create, read, update, and delete data.

The library is divided into two main components: SQLAlchemy Core and SQLAlchemy ORM. Core functions as a query builder, while ORM focuses on mapping database tables to Python classes. This design enables developers to work primarily in Python, enhancing productivity and reducing the complexity of database interactions ¹⁵.

SQLAlchemy is widely used in various web frameworks, including Flask and Pyramid, and is appreciated for its flexibility and performance. It can be utilized in both simple and complex applications, allowing developers to choose between using just the Core or both Core and ORM features based on their project needs ¹⁴.

If you’re interested in getting started with SQLAlchemy, there are numerous tutorials and resources available to help you learn how to implement it effectively in your projects.
