      Very handy. The ORM stuff is very useful. Certainly more of a desk reference than a step-by-step guide. Makes me feel good that I missed all of the DB hassle days of the last decade (for which SQLAlchemy provides many of the solutions).

      It was ok. However, the examples are a bit inconsistent and of course it is back in 2008, so a lot of things are out of date.
