Business Rules Engine
A Business Rules Engine (BRE) is a software system that executes business rules in a runtime production environment. It separates business logic from application code, allowing non-technical users to define and modify rules through a user interface or domain-specific language. This enables dynamic decision-making, process automation, and compliance management without requiring code changes.
Developers should use a Business Rules Engine when building applications that require frequent changes to business logic, such as in finance for loan approvals, insurance for claim processing, or e-commerce for pricing and promotions. It reduces development time by decoupling rules from code, improves agility by allowing business analysts to update rules directly, and ensures consistency and auditability across complex decision workflows.
