摘要
2.4m光学望远镜长时间运行必然产生海量数据。这些原始观测数据需要存储以备将来研究。为了利用这些观测数据,需要在2.4m远程观测系统中建立一个数据管理子系统。该系统可实现下列任务:数据的压缩、归档、实时浏览、数据检索、下载。此系统建立在Linux+MySQL平台上,使用J2EE技术开发。
Massive amount of data are expected to be generated after the start of the operation of the 2. 4 m optical telescope of the Yunnan Observatory. As future scientific results are based on these data, the data management is an important part of telescope operation. In order to safely preserve and efficiently utilize these data, we build a data management subsystem in the remote observing system of the 2. 4m telescope. This version of data management subsystem incorporates the following functions： data compression, data archive, real-time data browse, data search, data download, and more. The subsystem is built in the environment of Linux ＋ MySQL by using the J2EE technique.
