LAMOST控制系统实时分布式数据库

The Real Time Distributed Database for LAMOST Control System

介绍国家“九五”重大科学工程项目“大天区面积多目标光纤光谱天文望远镜(LAMOST)”中基于QNX(Quick UNIX)操作系统的实时分布式数据库的研究情况。此项研制已通过2002年7月2日由LAMOST工程指挥部组织的北京、南京和合肥三地专家的评审,并得到好评。该数据库功能强、工具丰富、操作方便,在类UNIX操作系统下实现了Windows的界面风格,可以满足LAMOST控制系统数据在线(或离线)处理、存储、程序生成表格和图形等需要,也可推广应用到其它相关领域。

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.
