基于非关系型数据库系统的近地天体望远镜图像数据库的设计与实现

Design and Implementation of CNEOST Image Database Based on NoSQL System

近地天体望远镜是我国最大的施密特望远镜,2006年投入运行以来,采集了超过3 TB的天文图像数据;2013年CCD相机升级后,图像数据将以每年超过10 TB的速度增长.对海量图像进行管理是其数据处理系统不可缺少的部分也是数据共享的基础.在需求分析基础上,设计并实现了基于非关系数据库的图像数据库系统.

The China Near Earth Object Survey Telescope （CNEOST） is the largest Schmidt telescope in China, and it has acquired more than 3 TB astronomical image data since it saw the first light in 2006. After the upgradation of the CCD camera in 2013, over 10 TB data will be obtained every year. The management of massive images is not only an indispensable part of data processing pipeline but also the basis of data sharing. Based on the analysis of requirement, an image management system is designed and implemented by employing the non-relational database.
