The Extreme Ultraviolet Explorer satellite (EUVE) mission has employed a Relational Database Management System (RDBMS) in several ways. Shortly after the launch of EUVE in 1992, an indexing scheme for the EUVE telemetry was implemented to facilitate access to the calibration, in-flight, and supplemental telemetry data. The RDBMS has been used for tracking EUVE observations and other administrative information. Over time it has evolved into the central data repository of the distributed EUVE data reduction system. The RDBMS was also used in a number of experimental systems. In 1992 EUVE began participating in the Astrophysics Data System where it used the RDBMS as the primary repository for the EUVE bright source list and additional, ancillary information. With the advent of the World Wide Web, EUVE used its RDBMS to publish dynamic information for use within the project and across the Internet. More recently, EUVE has created prototype client programs to facilitate use of relational databases for scientific applications. This work is supported by NASA contract NAS5-29298.
