The JBoss BRMS application helps users to solve problems in a declarative manner with business rules.

JBoss BRMS helps users organize, author, and maintain business rules. We covered a step-by-step BRMS installation, rule authoring, and testing. We implemented various business rules, including a decision table. We exposed a real-time decision server to serve money transfer fees on a REST interface using pricing rules defined by a decision table.
