SQLAlchemy
SQLAlchemy is a library for Python, providing powerful and flexible tools for working with relational databases. It combines the principles of object-relational mapping (ORM) and the capabilities of direct execution of SQL queries.

Technical Aspects
Drivers for various databases
SQLAlchemy supports many relational databases, such as PostgreSQL, MySQL, SQLite, and many others.
Query optimization
Automatic join, resolution of n+1 problem, caching tools.
Migrations
With tools such as Alembic, you can manage versions of your database and apply migrations.
Security
SQLAlchemy provides tools to prevent attacks such as SQL injections.
Capabilities
Automatic schema generation
SQLAlchemy can automatically generate a database schema based on your classes.
Flexible relationships
Supports one-to-many, many-to-many, and many-to-one relationships between models.
Composite keys
Ability to create composite primary and foreign keys.
Scalability
Thanks to the modular structure, you can easily add additional functions or integrate third-party solutions.
When is it better to use SQLAlchemy in projects?
Complex projects
When your project requires complex database queries or flexibility in data modeling.
Multifunctional applications
When you have a multitude of different models and relationships between them.
For large development teams
Thanks to migrations and a clear code structure, large teams can easily work with the same database.
If you need maximum performance
Although ORM may add some overhead, you can optimize queries and use the core for critically important parts of your application.
