Kris and I will do a Drools presentation for BeJUG on April 27th at 19h00 in Ghent (Belgium).
We will be talking about Drools Expert, Drools Planner, Drools Flow, Drools Fusion and more.
Here's a preview of the Drools Expert chapter, in which I 'll show a phone call billing use case. I 'll compare a pure Java, an SQL and a Drools implementation as the billing rules become more complicated.
Hope you to see you there!
