A fundamental component of the IUE Final Archive will be a comprehensive database containing a group of "core data items" to fully and accurately characterize the IUE dataset and to facilitate future analysis. As the Final Archive database is being populated, the accuracy of each of these core data items is verified. The database is housed in a commercial off-the-shelf (COTS) RDBMS allowing the data to be easily and flexibly accessed by the IUE Project and ultimately by users.

In addition, the database has become an integral component of the GSFC Final Archive Processing System. The database drives the processing pipeline and tracks the progress of each image through all four steps of the system beginning with core data item verification, through the pipeline processing and image screening subsystems, and ending with the archive interface with the National Space Science Data Center (NSSDC) where the data are made available to the astronomical community. The database is used effectively to control the queue of images in these subsystems, allowing the overall system to run with minimal human interface.

This work has been supported under NASA contract NAS5-31230 to Computer Sciences Corporation.
