In this blog entry I’ll look at Drools/JBoss Rules implementation of Alpha and Beta Nodes indexing. How such an index looks like. When it is created. What are the benefits. Some examples are also given.

Considering that a high-end BRMS (Business Rule Management System) costs about US$50,000 just to get started, and that annual maintenance, runtime fees, and professional services can drive the total toward a hefty half-million or more, organizations on a
Drools is an enhanced Rules Engine implementation based on the ReteOO algorithm, an algorithm adapted from the one originally devised by Charles Forgy. Drools has become quite popular due to performance characteristics and it’s natural language semantic
The famous golfer riddle - first published (as far as I know) by rule-celebrity Dr. Ernest Friedmann-Hill (creator of the JESS rule engine) in this online-article.
I made a decision to discontinue the Cut The Knot column. The column has a distinction of having straddled two decades, two centuries, and in fact, two millennia. It was never meant to last that long. I thank all the readers who cared to send me their sug
This article gives a practical introduction into the language Xcerpt, guided by many examples for illustrating language constructs and usage. Xcerpt is a rule-based, declarative query and transformation language for XML data. In Xcerpt, queries and the (r
Abstract: Set-oriented constructs for forward chaining rule-based systems are presented in this paper. These constructs allow arbitrary amounts of data to be matched and changed within the execution of a single rule. Second order tests on the data can be
JBoss Web is a web server and servlet container at the same time. It’s promise is that it can serve static and dynamic content, very fast, without the need of an Apache HTTPD fronting it. If that’s true, its party time, and I personally live for the d
New visual rule builder (Michael Neale) I have been beaving away on a new UI/rule modeller specifically for the web (well, at least the web initially, hopefully we will also do it stand alone in the plug in soon).
JBoss Seam is a "lightweight framework for Java EE 5.0". What does that mean? Isn't Java EE (Enterprise Edition) 5.0 itself a collection of "frameworks"? Why do you need another one that is outside of the official specification? Well, we view Seam as the
Overview This guide provides a step by step guide to setting up a functional, productive Seam development environment and deployment runtime. This guide will show you how to:
