Well, as this is the only dedicated book (at the moment) to what everybody is calling the best ORM out there, you expect a thorough walk-through and an excellent introduction to the product. It isn't. Let us put that in perspective: I know SQL (since the 80-ties), Python (likewise), I have developed C/S apps as well as Web-apps as well as ERP-applications and parts of Operating Systems, but I still can not get my head around what the author is trying to convey…

There exists better chapters about SQLAlchemy in other books, that blows the contents of this book away.

Sad to say, this is not recommended reading.
