The Interface Technology Of The Real-time Database For SIS In A Power Plant

This paper aimed at real-life meaning of data integration, designed a system. This system based on CORBA specification has been designed by JAVA and XML. The system has four layers, including application layer, data operation layer, data wrapping layer, and data source layer. A general data structure is provided in the paper, which can load any data that can be changed into relationship data. Because JAVA and XML are independent of platform environment, the code migration is very easy. CORBA can shield the heterogeneity of platform to realize the transparent query to data source by client. According to the research of Dynamic Information Public technology, this paper also presents a practical system. We take Microsoft Active Server Page as the tool to develop the whole system. ADO component makes it considerably easier to access data on database, so we can distribute data information dynamically.
