1. The quest for ‘certainty’ in an inherently-uncertain world is futile. Rules of all kinds exist to help human thinking and human judgment, not to act as a substitute for it.
2. The software vendors … are frankly not far short of committing fraud with many of the claims they make as to the efficacy and validity of their ‘business-rules engines’.The term business rule unfortunately has been hijacked by software vendors to mean something very different from the original concept. For example, production rules (the basis for the majority of current product offerings) are not business rules. Full stop. This distorted view of business rule needs to be rectified. Don’t let yourself be sucked into it! For real business rules there are three (optional) supplemental specifications for each business rule statement:
(1) level of enforcement
(2) violation (breach) response
(3) violation (breach) message.It is through these specifications that the richness of behavioral coordination can arise.
a computer program typically used to provide some form of artificial intelligence, which consists primarily of a set of rules about behaviorProduction rule systems are a class of platform whose rule format and operation are aimed toward developers. According to Wikipedia:
“A production system provides the mechanism necessary to execute productions in order to achieve some goal for the system. Productions consist of two parts: a sensory precondition (or ‘IF’ statement) and an action (or ‘THEN’). If a production’s precondition matches the current state of the world, then the production is said to be triggered. If a production’s action is executed, it is said to have fired.”
Aside: I have been using this same slide since 1994(!).Suppose you have a process or procedure that can be performed to take a customer order.
