Thanks for the kind words!
Post a review!
This book actually doesn't depend on a particular version or even product. It discusses general design techniques and guidelines such as how to design a database in general. That means it doesn't really need new editions when new versions of products (such as SQL Server or MySQL) come out.
That in turn means the publisher probably won't want to do a second edition for a year or two, and even then only if the book does fairly well.
Was there something in particular missing from that book that you would want to see in a new edition?
