QuestionsQuestions

JBoss BRMS
What is a rule?
● In short, a rule is an premise and conclusion
● If it is raining, then the ground must be wet
● A rule is made of conditions and actions. When all the
conditions are met, a rule may “fire”.
● The conditions are collectively referred to as the LHS (left
hand side) and the actions are referred to as the RHS (right
hand side, or consequence).
● A rule operates on facts (data). In our case, these facts are
instances of objects in our application.

JBoss BRMS
What is inferencing?
● We want to take all of our data (facts) and combine it with our
knowledge (rules) and come up with some conclusions
(inferencing)

Inference Engine
● The brain of a Production Rule System is an Inference Engine
which matches facts against Production Rules.
● When matches are found, the rules actions are fired.
● Actions most often change the state of the facts, or perform some
external action on the application.
