"This is an excellent book. It is relevant, readable, timely, and technically accurate. The author has a good handle on what is important to the industry, separating the hype from the practical solutions."
"Peter's book is rich with code examples that will help you understand exactly how to follow his footsteps to get a working system."
Building Scalable Database Applications: Object-Oriented Design, Architectures, and Implementation is a comprehensive and authoritative guide to building client/server applications by developing a stable and reusable business model. The business and database models illustrated in this book both address the unique challenge of manipulating object storage and retrieval from a developer's point of view.
Software engineers and programmers need this information to lead their development teams toward businesswide distributed software systems. This book demonstrates the pragmatic approach of integrating systems that are currently in use into a cost-effective and time-saving object-oriented system. The approach allows for the business model and the database schema to operate independently so that they can evolve individually, allowing them to be easily reused and maintained.
This is the first book to thoroughly cover scalable database applications; Building Scalable Database Applications focuses on building independent models that are free from all database and user-interface aspects.
