Read as support for my Son's CSE class. Having 30+ years in RDBMS solutions, was actually quite pleased on the approach and coverage this book provides.
Where this book really separates itself from the plethora of books available about SQL and Databases is that the book maintains a keen focus on the design decisions that go into creating a database, instead of simply finding a trivial example that demonstrates the syntax. Overall, I found the book to be very approachable, while at the same time not shying away from intermediate level topics.
