A brief research summary of a real time distributed database package on the basis of QNX OS is presented. This package is developed for the Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST), which is one of the national large scientific projects in the Ninth Five-Year Plan, and has passed a critical review and won positive response among the experts from Beijing, Nanjing and Hefei at the evaluation meeting on July 2, 2002, organized by the LAMOST Engineering Headquarters. The database package is powerful in functions, rich in development tools and easy to operate with a Windows style under UNIX-like operating system. It satisfies the requirement for online/offline data process, storage, programmable creation of tables and graphs for LAMOST control system. The database package can be adapted to the applications in other related areas.
