*by A***R on July 7, 2014*

This book is worth buying for lack of other resources, but could be a lot better. Starts off explaining some basics of how to get started with drools, but then rather then progress on how to solve hard and harder problems, it jumps to a reference book and just dumps all the rule conditions. It then seems to jump into some advanced topics such as how to migrate existing data or build dsls. As a reader I would have appreciated much more about common best practices, how to keep rules as simple and understandable as possible, how to abstract common logic in an environment with functions but no unification, etc.

### ⭐⭐⭐⭐⭐ Five Stars

Great book

### ⭐⭐ First impressions
*by L***H on January 30, 2014*

This book has a fairly narrow focus, which is just fine when one considers that the potential audience for the book is rather limited. That said, it does a decent job of presenting the information. It uses, as its primary example, the building of a system that has banking information as its primary domain. Throughout the building of the example system, the reader is presented with a series of domain scenarios (and Drools based solutions) that build on each other quite well.A cursory review of the table of contents promises the inclusion of a wide range of Drools related subjects. Covering everything from a basic introduction to declarative, to digging into the Rete algorithm for performance tuning, is a daunting task.The author starts out by providing a simple overview of declarative programming concepts. He goes into the advantages and disadvantages of this approach to building systems, all the while building up a case for using Drools. At the end of the first chapter, Michal tells the reader what is coming up next; including a "look at how to set up the development environment..." The problem is that the next chapter opens by telling the reader to go to Appendix A to read about how to set up the development environment. Unfortunately, this inconsistency in the flow was not limited to this single incident.The instructions that were given (in Appendix A) for how to set up the development environment were adequate. They did not give much instruction as to how a reader would actually install Drools for development, rather it mainly pointed the reader to the Drools/jBPM web sites. The author did provide some example entries for the maven pom files.Going back to the main path through the book, the author did go on to give instruction (mainly through example) on the basics of writing rules, and the Java code to exercise them. As stated above, the inconsistency in the flow of the book was not limited to one or two incidents. Each chapter seemed to jump from syntax instructions, to the explanation of conceptual ideas, to various "tips"; without any consistent pattern. All of these elements are then interspersed with bits of example code.I could go deeper into each chapter, but in summary, I was a little disappointed by this book. I had read, and actually got most of my early Drools education, Michal Bali's earlier tome on Drools 5.0. This follow up just didn't seem to be as useful as that earlier book.
