Abstract

A database system has been implemented for the L3-experiment at the CERN electron-positron storage ring LEP. It provides management and decision support information on construction schedule and funding profile. The programs are written in FORTRAN and run on the VAX computer, the standard of the L3-collaboration. Each responsible of the ten sub-assemblies provides a quarterly update on both progress and finance of approximately 100 tasks using interactively the project monitoring program on his local VAX. Via LEP3NET these files are then transferred to CERN where two program-chains provide barchart stile displays and/or printouts with automatic warnings in case of cost overrun or schedule problems.
