Abstract: In order to implement real-time monitoring and controlling of data in configuration software, the system adopted physical RAM as the main storage area of real-time database (RTDB) to store, manage and operate the data in real time, and proposed commercial database based RTDB of configuration software by using SQL Server 2000 database for management of history data. By object-oriented and multi-thread methods of programming, the system adopted direct orientation of pointers search method to solve the problem of compatibility with Windows Software. The test results indicate that the purpose of real-time monitoring and controlling is achieved by this system.
