regelmodules

Regelmodules are modular units of business rules used in rule-based systems and business rule management systems (BRMS). They encapsulate a cohesive set of rules, decision tables, and related artifacts so they can be developed, tested, deployed, and versioned independently. By isolating rules into modules, organizations can manage domain-specific logic with greater reuse and clearer governance.

A regelmodule typically contains rule definitions expressed in a rule language, input and output schemas, metadata, and often tests or property checks. It may declare dependencies on other modules and specify version information, so that large rule bases can be composed from smaller, interoperable pieces. Execution by a rule engine proceeds by loading the relevant modules, instantiating working memory with facts, and applying applicable rules according to priority and activation strategies.

Modules are managed through a lifecycle that includes authoring, validation, packaging, deployment, and monitoring. Metadata such as authors, domain, validity period, and test coverage support traceability. Change management practices help assess the impact of modifications and prevent regressions.

Benefits include improved modularity, reusability across products or processes, easier testing, and faster iteration on business rules. They are commonly used to implement credit checks, pricing logic, eligibility decisions, or compliance checks, where different contexts require different rule sets but share a common engine.

Challenges include managing dependencies and version conflicts, ensuring consistency across modules, performance overhead, and the need for good governance and testing to avoid rule conflicts or unintended behavior.
