Executive Summary

In several working environments, production involves repeated executions of certain procedures. A workflow describes the individual tasks performed in these procedures and their interrelationships. Current Workflow Management Systems (WFMSs) use a Database Management System (DBMS) to store task descriptions, and implement all workflow functionality in modules that run on top of the DBMS. Motivated by scientific workflows, authors propose a much more DBMS-centric architecture, in which conventional database technology provides much of the desired scientific WFMS functionality. A key element of the approach is viewing the workflow as a web of data objects interconnected with active links that carry process descriptions.
