Database Design for Railway Traction Power Supply Supervisory System

The various functions of railway traction power supply supervisory system are based on a database. While the database system, the performance of which will influence the performances of the supervisory systemgreatly, is one of the most important components in the traction power supply supervisory software. Based on the operational characteristics of the supervisory system, this paper focuses its discussion on the data model, database structure, database design and creation of the traction power supply supervisory system respectively.
