Methods, mediums, and systems are described for providing a platform coupled to one or more rules engines. The platform may provide runtime rule services to one or more applications. Different rules engines may be used for different types of rules, such as calculations, decisions, process control, transformation, and validation. Rules engines can be added, removed, and reassigned to the platform. When the platform receives a request for services from an application, the platform selects one of the rules engines to handle the request and instructs the selected rules engine to execute the rule. The rules engine may be selected automatically. The platform may be implemented through a service-oriented architecture.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A system for facilitating communication between one or more applications and one or more rules engines, the system comprising: a design tool configured to provide a platform syntax for defining rules for the one or more applications and to associate each rule with a respective predetermined one of the one or more rules engines, wherein the association of each rule with the respective predetermined one of the rules engines is based on predetermined criteria; a rule processor configured to translate each rule defined using the design tool from the platform syntax into a rules engine syntax of the respective predetermined one of the rules engines; a repository configured to store each rule, each translated rule defined using the design tool, an association of each rule defined using the design tool to its respective translated rule, and the association of each rule defined using the design tool with its respective predetermined one of the rules engines; and a rules execution platform configured to receive a request from one of the applications to execute one of the rules defined using the design tool, identify the respective predetermined one of the rules engines associated with the requested rule, and transmit the requested rule to the respective predetermined one of the rules engines associated with the requested rule. 2. The system of claim 1 wherein the predetermined criteria comprises an environment in which the design tool is initiated. 3. The system of claim 1 wherein the predetermined criteria comprises information corresponding to a user that defined the requested rule using the design tool. 4. The system of claim 3 wherein the information comprises a role of the user. 5. The system of claim 4 wherein the role comprises a functional role of the user. 6. The system of claim 1 wherein the design tool is configured to present various views depending on a role of a user accessing the design tool. 7. The system of claim 6 wherein the role comprises a system role.
