MECHANISM TO ABSTRACT FACT TYPES FROM A RULE ENGINE

Some embodiments of a fact type abstraction mechanism of a rule engine have been presented. In one embodiment, a fact type abstraction layer is provided to a rule engine core to allow the rule engine core to access facts of multiple different types. Further, the rule engine core is used to process the facts of multiple different types against a predetermined set of rules without converting the facts of multiple different types into a native type.
