a simple business rule management system for php
------------------------------------------------

[](#a-simple-business-rule-management-system-for-php)

Wikepedia definition :

> 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.

Inspired by the book Enterprise Patterns and MDA written By Jim Arlow and Ila Neustadt
