Warning: Read before buying!
10. August 2005
Format:Taschenbuch
As a C++ developer recently tasked to design a "rules-engine" for a real-time application, I purchased this book with the hope of discovering an alternative to a "true" rule-engine (i.e., one that utilizes rule chaining and a pattern matching algorithm).
Although this book does give a step-by-step description of how to implement a "rules-engine" using Microsoft Access and Visual Basic for Applications, there is absolutely no discussion of how a rules-engine could be implemented in any other development environment.
The relevant material in the book could easily be presented in about 200 pages or less. Rules are not really addressed until chapter 15. Most of the early chapters deal with such topics that are tangential at best. Just one chapter discussing the differences between the type of rule-engine described in the book and an expert system type of rule-engine would have made the book useful.

Practical aspects of business rules
7. März 2004
Format:Taschenbuch
Although this book's title may lead you to believe it is solely about developing a business rules engine, it is much more. First, to answer the question that developers may want to know about the book - yes, there is code and it can be downloaded from the web site that supports the book. However, in my opinion, the real reason to buy this book is to gain a deeper understanding of the practical aspects of incorporating business rules into applications. Where books such as "Principles of the Business Rule Approach" (ISBN 0201788934) cover the subject well from the conceptual and systems analyst perspectives, this is the only book to approach business rules from a tools and integration perspective.
Topics range from data modeling to working with batch processes, and every relevant consideration in between. You'll find that the author heavily favors the use of reference data, which is no coincidence because he wrote, in my opinion, the definitive book on that topic as well - "Managing Reference Data in Enterprise Databases" (ISBN 1558606971). More importantly, though, is how thoroughly this book covers all issues associated with developing and implementing a business rules engine, especially with respect to enterprise data architectures and associated databases.
If you have mastered the concepts of business rules and are ready to implement them this book is the place to start.

excellent technology primer for this subject area
23. März 2008
Format:Taschenbuch|Von Amazon bestätigter Kauf
As a database designer and programmer for over a decade, I had always wondered how a business rules engine might actually be implemented. What were the neccessary "parts"? What was the overall technology strategy for turning documented rules into executable actions? What might an interface need to look like, and what functionality would it need to offer to support a working business rules engine? All these questions are answered in this book. The implementation design provided (as working code in Microsoft Access and VBA) is not "enterprise" ready in the sense that is would support hundreds of users and tens of thousands of business rules. But it is a comprehensive "proof of concept" - with working code - that clearly addresses design and implementation strategies and methods required for these engines. This book has now surely given me more understanding about how these engines can work than probably anyone else has in my organization of over 1000 employees (that admittedly has never implemented this type of funtionality but may very well need to do so sometime in the future).
Prerequisites for understanding this tutorial would be sound understanding of relational database theory (what effective information processing systems do not require this understanding?), good basic understanding of conventional database development concepts, as well as understanding of typical data processing required for both interactive data entry and batch processing of data.
