Abstract: In this paper, an architecture of engineering database query processing system based on CORBA is presented. The architecture supports the system to retrieve the engineering data crossing hardware platforms, OSs and integrating heterogeneous databases' information. Furthermore, the architecture is convenient to process the subquery parallel and asynchronously so it can improve efficiency. ;;;;
