A production database system for the LHCb VELO modules

This paper will describe the design of the database system and the web interface which allowed all QA and test data to be logged in real time and enforced a procedural control during the production of the LHCb VELO modules at Liverpool University. It recorded the QA status of all components and associated test data and displayed the data via a dynamic web interface. It was an essential management tool and allowed for a paperless production environment. It is now a repository of all the production history and test data, and will be maintained as a resource for investigation of any problems which may arise in the future.
