Workflows are activities involving the coordinated execution of multiple tasks performed by different processing entities. Workflow management systems support the specification and execution of workflows. WorkMan is a prototype of a workflow management system in which considerable attention is paid for the utilization of the services of database systems. Particularly the use of SQL-features in implementing workflow scheduling and supporting the transactional properties of workflows are investigated. In the WorkMan prototype the scheduling of tasks in based on SQL-triggers while the transactional properties of workflows (isolation and atomicity) are implemented using SQL-assertions and CHECK-constraints.
