This is a beautiful, accessible, up to date, patient, didactic, and all in all a very good book. A Dutch teacher of databases since a long time, I never came across quite the right thing for my non-Dutch students until I found this one.
Watson is not a computer nerd. He appreciates the fact that data modeling problems are real-world problems. And the fact that modeling and SQL are two sides of the same coin: getting the data IN a database in order to get information FROM it. And that fact that databases operate in an organization, not in a vacuum.
