deductive database


A combination of a conventional database containing facts, a knowledge base containing rules, and an inference engine which allows the derivation of information implied by the facts and rules.

Commonly, the knowledge base is expressed in a subset of first-order logic and either a SLDNF or Datalog inference engine is used.
