Business Objects:

Re-Engineering for Re-Use - 2nd Edition

The aim of this book is to show you how to use business objects to re-engineer your existing information systems into models—and so systems—that are not only functionally richer but also structurally much simpler. It is a practical guide to re-engineering your systems; when you finish reading it, you will be ready to start. (Business objects can also help you to re-engineer the underlying business that is processed by these systems).
