US Patent 7917501 Optimization of abstract rule processing

Embodiments of the invention provide techniques for optimizing the processing of abstract rules. In general, the results of executing an abstract query may be used as data inputs for processing an abstract rule. In one embodiment, query results may be sorted according to input field values required for processing a deterministic abstract rule. If a record of the sorted query results includes the same input values as a preceding record, then the rule output of the preceding record may be reused, rather than processing the abstract rule again. Accordingly, the demand load placed on a rule engine may be reduced.
