Query: Dashed Expectations

I'm a seasoned data modeler and was hoping I'd found a book to use for quickly training new members of my team. I was very disappointed. The data models presented in this book are so generic that they are useless to all but the most inexperienced data modeler, and even that usefullness is questionable. It's a great idea-- compiling a book of reuseable data models from various industries and subject areas-- but this book misses the target, badly. Let's hope for a better 3rd edition.
