visual rules® is used to graphically model business rules and generate program code as well as documentation of these rules. How rules are processed is defined in the models. They precisely represent the business logic. In this way business rules become transparent and can easily be customized to new business requirements. The generated program code is ready to integrate in enterprise applications. No inferences are used - one reason for the programming code to be high-performing. The rule models can also be deployed as EJB on all application servers that conform to J2EE standards, e.g. SAP Web AS and IBM WebSphere. The business rules can also be executed ad-hoc within visual rules, without being integrated in any application. Please find all release notes here:
