    MySQL is a relational database system that is widely used in ATLAS for storage of constants (e.g. calibration constants, NOVA parameters) and metadata. The ATLAS MySQL distribution is installed at /afs/usatlas.bnl.gov/offline/external/mysql .

    U.S. ATLAS Tier I facility has the following MySQL servers (visible on web, user/pass is usual for ATLAS web sites):

    Note on MySQL servers at CERN. ATLAS MySQL server at CERN is atlasdev1.cern.ch.At this time (Jan. 2004) both U.S. and CERN MySQL databases are used by ATLAS software. U.S. ATLAS Tier I Facility does not maintain the copies of CERN databases and vice versa.
