Negative Positive
Title: Very disappointing
Review: I bought this book based on some of the enthusiastic reviews here but was very disappointed. I think people who see rules engines as the next big thing and are very excited about it may be enthusiatistic about this book because it pushes that line very hard. However, there is very little in this book that reflects hard practical experience or that is likely to surprise an experienced software designer with a basic understanding of rules engines. Good books on this subject are still waiting to be written.Instead of this book I would recommend reading "Domain-Driven Design: Tackling Complexity in the Heart of Software" by Eric Evans and the documentation for whatever rules systems you are considering.
Is the review positive or negative?
