Business Rules
Business rules are explicit, formalized statements that define or constrain aspects of business operations, decisions, or data. They are used to guide behavior, enforce policies, and ensure consistency in business processes, often implemented in software systems to automate decision-making. Examples include validation rules, pricing calculations, eligibility criteria, and compliance requirements.
Developers should learn and use business rules to build adaptable, maintainable, and compliant software that aligns with organizational needs. This is crucial in domains like finance, healthcare, and e-commerce, where rules frequently change, as it allows for easy updates without modifying core code. Implementing business rules separately from application logic improves clarity, reduces errors, and supports regulatory adherence.
