JRules is a business rules management system (BRMS) developed by IBM, designed to help businesses automate and manage decision-making processes. It allows organizations to define, execute, and monitor business rules and policies in a flexible and efficient manner. JRules provides a platform for creating rule-based applications that can adapt to changing business environments without requiring a complete system overhaul. It integrates well with other enterprise systems and is often used for applications in finance, insurance, and customer service. JRules is known for its ability to decouple business logic from application code, making applications more agile and easier to maintain.
