Rule-Based Design
Rule-Based Design is a software development methodology that structures systems around explicit, declarative rules that define behavior, logic, or constraints. It involves creating a set of rules (often in a rule engine or knowledge base) that govern how the system responds to inputs or events, enabling flexible, maintainable, and transparent decision-making processes. This approach is commonly used in applications requiring complex business logic, expert systems, or dynamic configurations.
Developers should learn Rule-Based Design when building systems with frequently changing business rules, such as financial applications, insurance claim processing, or compliance engines, as it allows non-technical stakeholders to modify logic without code changes. It's also valuable for creating expert systems in AI, medical diagnosis tools, or fraud detection, where transparent, auditable decision-making is critical for trust and regulatory compliance.
