What is Business Rules Engine?

A Business Rules Engine (BRE), also known as a rules engine or business rule management system (BRMS), is a software system that executes one or more business rules in a runtime production environment. These rules are typically defined and managed separately from the application's core code, allowing for easier modification and adaptation to changing business requirements. BREs are commonly used for automating decision-making processes, policy enforcement, and complex calculations. They allow businesses to implement changes to business logic without modifying code.
