US Patent 7934219 Process agents for process integration

The addition of process agents into an application system allows a much simpler integration between business objects by placing the integrating components into separate, independently updateable process agents. Process agents observe business objects with which they are associated and communicate with other process agents. Alternatively, process agents may be notified by business objects to perform communication activities. Thus, a business object may be designed, operated, or updated with complete independence from the surrounding structure of the application system. The logic, application code, and integration components that require specific changes or design in response to changes in the overall application system or real world conditions are placed in the process agent objects, allowing them to be updated, modified or integrated freely without any changes to business objects within the system.
