Pony ORM

Pony ORM is a Python Object-Relational Mapper that allows developers to work with databases using Python objects and queries written in plain Python. It translates Python queries into optimized SQL, supporting SQLite, PostgreSQL, MySQL, and Oracle. The current version is 0.7.19. Releases occur periodically, often driven by new Python version support or significant bugfixes, indicating an active but not rapid development cadence with several months to a year between minor releases.
