Exploring SQLAlchemy

Exploring SQLAlchemy

This project provide a sandbox to experiment with SQLAlchemy. This idea is to build an example sequentially in steps to give new users the idea on where to start and how to progress.

Along the way some principles will be exhibited. The code should be self-explanatory.

The source code in src by itself does not do much, it basically only defines the tables and some setup code. The “examples” are in the the pytest's since we are experimenting to see howe it works and if it was successfull.
