Migration and Heterogeneous Database Integration in JOPENS System

This paper introduces a method of using MetaMatrix middleware to realize the migration of JOPENS system from MySQL database to Oracle database by building virtual database. It solved the integration of the latest data center platform and the seismological JOPENS system of Shanghai Seismological Bureau, and ensured that the entire heterogeneous database migration process was seamless and smooth. Such an attempt provides a reference for the migration and integration of heterogeneous databases for seismic services.
