What do you mean by "rule based system"? 
Do you mean rules in the sense of 

1) declarative logic programming (or deductive databases) 
for defining derived concepts and heuristics (without any 
state-changing effects)? These rules are called "derivation 
rules" in RuleML.

2) SQL triggers (or "event-condition-action rules") for 
specifying the reactive behavior of a system in response to 
events? These rules are called "reaction rules" in RuleML. 
They specify state changes in their head/consequent, and 
they may "call" derivation rules in their body/antecedent.

3) production rule systems like JESS? They are just another
programming language based on the rule metaphor but without
any precise semantics for rules.

Notice that this list is only concerned with a restricted
form of 1).
