I have read it :-)

(Disclaimer: I'm the lucky sod who was Chris's editor for this book)

It's a good read. Chris forces you to think. I learned a lot about relational theory while editing the book. For example, the idea that a table's header is a predicate, and that each row in the table is a proposition, that was a novel idea that I'd not heard before. Yet it underlies much of what we do. It's something I *should* have understood years ago. Frankly, I fell squarly into Chris's target audience myself.

BTW, if anyone is curious about the MP3 player using a relational database (mentioned on Chris's back cover). The one I had in mind is the Phillips Micro Audio Jukebox HDD070/17:

http://www.consumer.philips.com/consumer/catalog/product.jsp?activeCategory=&language=en&country=US&catalogType=CONSUMER&productId=HDD070_17_US_CONSUMER

This player uses SQLite to keep track of the songs. There's at least one other player (also a Phillips?) that uses SQLite. I don't remember what that one is though. I'd have to ask our SQLite author.
