Best for

✓ Best for

Developers who need to interact with databases using Python dictionaries and want to avoid manual SQL queries.
Small projects or prototypes where setting up complex database interactions is not feasible.
Educational purposes for teaching basic database operations in Python.

✓ Best for

Developers building web applications that require robust database interaction using Python.
Teams working on projects where the ORM layer needs to be highly customizable and flexible.
Projects requiring support for multiple database backends without changing much of the code.

Not ideal for

✕ Not for

Projects requiring real-time data processing or streaming capabilities.
Large-scale applications needing advanced database features like sharding, replication, or distributed transactions.

✕ Not for

Projects that do not use Python as their primary language.
