This document describes a data processing system for database management. The system includes a registry management server in communication with a logical registry in a data repository. The data repository includes profile data associated with profile objects, a library of electronic instruments and a logical table including a number of logical rows corresponding to the profile objects. The registry management receives profile data from a client device, selects electronic instruments from the library, and maps the electronic instruments and profile objects by updating the logical table and indexing the logical table.
