A research on heterogeneous database integration in dispatching automation system based on CORBA

In order to realize the dispatching automation system resources sharing and efficient utilization, this paper first discusses the problems that heterogeneous database integration in dispatching automation system faced, nd the necessity of the system integration. On the basis of the introduction to CORBA, it made a study of the integration of heterogeneous database, making a detailed analysis of integrated system and its design. After that, a three-layer structure of heterogeneous database integrated system was presented, and the structure was based on CORBA. Further, this paper expounded the advantages of the database system. In the last place, it discussed the subsistent problems and future development of this system.
