In several working environments, production involves re-
peated executions of certain procedures. A workflow de-
scribes the individual tasks performed in these procedures
and their interrelationships. Current Workflow Manage-
ment Systems (WFMSs) use a Database Management Sys-
tem (DBMS) to store task descriptions, and implement all
workflow functionality in modules that run on top of the
DBMS. Motivated by scientific workflows, we propose a
much more DBMS-centric architecture, in which conven-
tional database technology provides much of the desired
scientific WFMS functionality. A key element of our ap-
proach is viewing the workflow as a web of data objects
interconnected with active links that carry process descrip-
