Abstract

Improvements made to a relational database management system (DBMS) developed for real-time energy management and control systems for electric utilities are described. The focus is on the software performance improvement features and the dual database concept for coordinated updates. The discussion covers task structuring, buffer usage, active restructuring, and presolving of access routes. Some of these features are applicable to other real-time systems with large databases shared by many application programs. The extension of the DBMS design for use in a hierarchical real-time system is described
