Object-Oriented Database Design Clearly Explained

the long version

"If you or your company is heavily invested in a relational database system, someone somewhere has probably told you that you should consider going object-oriented - whatever that means. Although object orientation is well understood and accepted in application development, its role in database systems is just beginning to emerge. The lack of an accepted standard only adds to the uncertainty. This book will help you make sense of the conflicting theories and vendor claims about object-oriented database systems."--BOOK JACKET.
