Abstract

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. A number of experimental systems also used the RDBMS. In 1992 EUVE began participating in the Astrophysics Data System, using the RDBMS as the 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.
