Business Rule Engine
A Business Rule Engine (BRE) is a software system that executes one or more business rules in a runtime production environment. It separates business logic from application code, allowing non-technical stakeholders to define, manage, and update rules without modifying the underlying software. This enables dynamic decision-making, compliance management, and process automation in applications.
Developers should use a Business Rule Engine when building applications that require frequent changes to business logic, such as insurance claim processing, loan approvals, or pricing engines, to reduce development overhead and improve agility. It is particularly valuable in regulated industries where compliance rules change often, as it allows business analysts to update rules directly without code deployments.
