Query: A really good book.

I read this book a few years ago and I remember it to bea pretty decent book on design. It doesnt claim to teach youhow to do UML or Java. There are other books specifically forthat. Highly recommended if you want to learn about good design.Books like these are *rare*. I am not sure what the reviewers whogave this a low score were looking for in this book.
