The Management of CMS Detector Data from Design to Operation

The nature of CMS construction is heavily constrained by time and budget, evolves with time and is highly distributed. Changes in CMS component design need to be tracked and quickly reflected in the production process. In industry, engineers employ Product Data Management (PDM) systems to control access to documented versions of designs. Workflow management systems (WfMS) [1] are employed to coordinate the complex and repeatable work processes of production. Workflow products cannot, however, support the dynamic activities found in the design stages of product development and in rapidly evolving process definitions and PDM systems are seldom used beyond design. Continuity from design to operation is therefore not facilitated by commercial products.
