Rule Engine
A Rule Engine (often referred to as an Expert System, Business Logic Engine, or Inference Engine) is a piece of software (or possibly hardware, if speaking about a dedicated Rules Engine SERVER) designed for creating, manipulating, modifying, parsing and evaluating rules created about a given object and/or relationship between multiple objects.
Business Rules Management Systems (BRMS) are related to Rule Engines in that they have an internal Rule Engine but also provide a user-facing, simple to use front-end for creating, evaluating, diagnosing and reporting on performance/outcome histories of rule bases.
