Imagine a different way to program in which you specify rules and facts instead of the usual linear set of instructions. That's the idea behind rule-based programming. A rule engine automatically decides how to apply the rules to your facts and hands you the result. This approach is ideal for expressing business rules and is increasingly used in enterprise computing.
Jess is a popular rule engine written in Java. It's supported by Sandia Labs and has an active online community. If you have a problem that can be solved with rules, Jess in Action will show you how. (If you are not sure, read chapter 2.) Written by the creator of Jess, this book is an accessible and practical guide to rule-based system development in Java.
about the book
Jess in Action first introduces rule programming concepts and teaches you the Jess language. Armed with this knowledge, you then progress through a series of fully-developed applications chosen to expose you to practical rule-based development. The book shows you how you can add power and intelligence to your Java software.
