"... Basically this question is isomorphic to asking if your database should be an EJB." Geez, drown the poor guy. Besides I thinks its more a matter that the components are orthogonal Seriously, wishing to help but not offend, may I recommend you purchase a book on analysis and design? A

RDBS Options Re: JESS: Questions on when to use Rule BasedSystem

2000-06-07 Thread Greg Ball
There may be a third answer to the RDBS / RBS integration question, or at least we are attempting it. One of our problems is rollup state, where the state of an object is dependant on the state of all its children, each of those objects is dependant upon the state of their children..etc. Wha
