Abstract

When migrating legacy database systems to a new database system the relationships between tables need to be preserved. Also, base tables and their children have to maintain their relationship. A database system which creates a system generated unique key is stored with the data which is loaded. To enable load, search, and retrieval to be efficient a data remapping function is defined which uses the system generated key to maintain the relationships which were maintained by a unique key in the legacy systems.
