US Patent 7996384 Query based rule optimization through rule combination

Embodiments of the invention provide techniques for optimizing the processing of abstract rules included in rule set containers. In one embodiment, a first abstract rule may be identified as having an effect on a second abstract rule of the rule set container. A predicate and an action of the first abstract rule may be used in translating the second abstract rule into an executable rule. The executable rule performs the functionality included in the first and second abstract rules, while only requiring one rule execution in a rule engine. In another embodiment, the first abstract rule may be translated into a rejection query configured to return a rejection set. The second abstract rule may be translated into an executable rule that includes a condition that excludes any records included in the rejection set.
