ABSTRACT:
A computer-implemented method is provided which helps to render the differences between relational database management system (RDBMS) types transparent. The computerized process enables database objects and authorizations on objects, as well as user privileges, to be moved or copied from one RDBMS to another within a distributed relational database environment without requiring a database administrator to have expertise in every RDBMS type in that environment. The computerized process is achieved using three inter-related and inter-dependent tables, a translation table, an implications table and a composition table which are stored in a computer memory and accessed through a computer. These tables provide a mapping matrix between database objects of a plurality of RDBMSs.
