TriGS flow Active Object-Oriented Workflow Management

We present the multi-paradigm architecture TriGS flow for a workflow management system. TriGS flow is based on an active extension of the commercial object-oriented database system GemStone TM. TriGSflow takes full advantage of the capabilities of the underlying database system such as reliability, recovery, transaction management, and authorization. At the current stage of implementation the novel features of TriGS flow are the seamless integration of ECA rules into an object-oriented model, the flexibility of workflow specification due to rule modeling, and the integration of external applications as part of workflow processing.
