Database independent migration of objects into an object-relational database

CERN´s (European Organization for Nuclear Research) WISDOM project deals with the replication of data between homogeneous sources in a wide area network (WAN) using the eXtensible Markup Language (XML). The last phase of the WISDOM (Wide-area, database Independent Serialization of Distributed Objects for data Migration) project, indicates the future directions for this work to be to incorporate heterogeneous sources as compared to homogeneous sources. This work will become essential for the CERN community once the need to transfer their legacy data to some other source, other then Objectivity, arises. Oracle 9i - an object relational database (including support for abstract data types, ADTs) appears to be a potential candidate for the physics event store in the CERN CMS experiment. Consequently this database has been selected for study. As a result of this work the HEP community can have a tool for migrating their data from Objectivity to Oracle9i.
