Explicit statements that describe or constrain aspects of a business to guide decisions and operations.
DESCRIPTION
Business rules express policies, constraints, and definitions that govern processes and data. They can be declarative (e.g., eligibility) or structural (e.g., unique identifier constraints). Externalizing rules improves transparency, maintainability, and compliance. Rules are often implemented via rule engines, decision tables, or validations in data pipelines. SBVR and DMN provide standards for representing business rules and decisions.
