Abstract
Workflow management systems (WFMS) execute a multitude of process models including a network of potentially distributed activities. WFMS store WFMS state information on the process models, the process model instances currently executed by the WFMS, together with the instances's state and the state of the WFMS themselves, in Database Management Systems (DBMS). The WFMS engines encompassing a set of control functions are implemented directly within the DBMS. Only stubs corresponding to these control functions need be implemented within the WFMS. The stubs exploit the services of the control function cores within the DBMS. Such implementation architectures can increase performance of WFMS significantly as the control functions can operate on and within those computer systems which store the data on the WFMS state.
