  • Method and apparatus to facilitate interaction management between loosely coupled applications
    Patent number: 6895408
    Abstract: One embodiment of the present invention provides a system that facilitates interaction management between loosely coupled applications. The system operates by first receiving one or more Data Tokens at a Databus. A Databus is a computing process, which provides persistent storage, computation services, and scheduling services. The system stores these Data Tokens in a matching queue within the Databus. Next, the system creates a Data Token entry within data tables, which specify the Data Tokens stored in the matching queue. A matching process matches the Data Token with registered Reactions in the Reaction matching tables. These Reactions specify the persistent query or exclusive interest of Data Tokens required for performing a service. When all Data Tokens required for the service are available, the system places a scheduling entry in a scheduling queue to schedule the execution of the matched Reaction that provide the requested service.
