Mical Bali has written an article on CEP, so thought i'd link it in.
In this article, by Michal Bali, author of Drools JBoss Rules 5.0, we'll look at implementing a banking fraud detection system. It is an ideal candidate for CEP. The volume of events in a banking system is huge and we need to be able to do complex decisions based on these events.
We'll specifically cover:
* CEP and ESP
* Drools Fusion
* Fraud detection
