A business rule engine (BRE) is a specific collection of design-time and runtime software that enables an enterprise to explicitly define, analyze, execute, audit and maintain a wide variety of business logic, collectively referred to as “rules.” A BRE can be purchased independently or comes embedded in a business process management suite (BPMS). A BRE enables IT and/or business staff to define rules using decision trees, decision tables, pseudonatural language, programming-like code or other representation techniques.
