Rule Engines and Declarative Programming Come to Java [Aug. 19, 2004] In the past one year a lot of attention has been given to rules engine and declarative programming. Having worked for 4 yrs on Rules driven enterprise projects, this kind of attention to this field seems pretty exciting. At Selectica I was involved in implementing business solutions using Selectica technology, and it gave me a good insight on this world. But I learnt more about the technology when I came out. Almost all Rules engines pretty much implement the famous Rete Alog, and all claim to do bunch of things. I really wanted to design rules engine which can be used to drive "agent software". I believe that rules driven agent software could prove to be a 'disruptive' technology.
