Abstract：In view of the characteristic of data and requirement of process control system for tandem cold rolling, data structure was designed on the basis of the joint application of Oracle 10g and Microsoft Visual Studio 2010. To achieve the data- caching and data reliability, a new data buffer mechanism for database was put forward, the method of accessing Oracle database through OO4O was established, and meanwhile, the method of creating shared memory through template class was also achieved. After that, actual data gathering functions by event, timer and message were provided, and then database manipulation was realized through Oracle database triggers. Ultimately, the database of control system for tandem cold rolling process was developed, and it was put into practical production. The application results showed that owing to the database system which is applicable for industrial production, the real- time for online database could be effectively guaranteed, the programming could also be greatly simplified, and then the efficiency of process control system could be improved.
