Evaluation of object-oriented database for distribution network monitoring system

This paper outlines an original object-oriented database management system which is designed for industrial applications and describes results of an experiment to apply it to a graphical user interface in a power distribution monitoring system. Database management systems are widely used and achieve high productivity and high reliability of data management in the business field and in some engineering areas. However conventional database systems, especially relational database systems, are rarely used in industrial real-time fields. This paper presents advantages of object-oriented concepts for modeling complex data of a monitoring system. The object-oriented database successfully supports data-modeling requirements of GUI applications, and the performance is well acceptable for GUI applications.
