Abstract

Although database migration has not yet been extensively researched, three predominant software solutions have evolved: language interfaces, source-code conversion, and data propagation. The authors consider how Swiss Bank and IBM designed and developed the IBM Data Propagator MVS/ESA, which supports interactive and batch data propagation. This software migrates data from the hierarchical IMS to the relational DB2, without affecting existing applications. It supports forward and reverse data propagation, which lets heterogeneous databases coexist. At Swiss Bank, the Data Propagator MVS/ESA handles the main customer and account databases at all five computer centers in Switzerland.<>
