A BRMS or Business Rule Management System is a software system used to define, deploy, execute, monitor and maintain the variety and complexity of decision logic that is used by operational systems within an organization or enterprise. This logic, also referred to as business rules, includes policies, requirements, and conditional statements that are used to determine the tactical actions that take place in applications and systems.

A BRMS includes, at minimum:

* A repository, allowing decision logic to be externalized from core application code

* Tools, allowing both technical developers and business experts to define and manage decision logic

* A runtime environment, allowing applications to invoke decision logic managed within the BRMS and execute it using a business rules engine
