The Scripps Orbit and Permanent Array Center (SOPAC) collects,
archives, analyzes, and disseminates data and data products from various
continuously
operated GPS arrays. To better facilitate the large quantities of data, SOPAC
has increased it's archiving capacity and implemented an Oracle 8i Relational
Database Management System (RDBMS). This has resulted in the on-line
availability of 1.75 Terra Bytes of continuous GPS data as far back as 1990.
FTP data transfer from SOPAC's GARNER archive has increased dramatically over
the last year due to these developments and has resulted in approximately
400,000 datafile transfers each month. The powerful features of the RDBMS are
currently integrated into SOPAC's archiving and processing operations. Web
based
applications have been developed that utilize this system in order to improve
the functionality and user friendliness of the SOPAC web-interface.
