ASO-S卫星工程科学应用系统的数据库设计

The Database Management Analysis for the ASO-S Science Operation and Data Center

先进天基太阳天文台(Advanced Space-based Solar Observatory,ASO-S)卫星是我国首颗太阳观测卫星,主要观测太阳耀斑和日冕物质抛射以及产生它们的磁场结构.ASO-S卫星的科学应用系统是科学卫星工程的6大系统之一,它连接科学用户和卫星数据,为将卫星的科学数据转化为科学成果提供保障.科学应用系统的数据库是连接软件与海量数据的枢纽,为科学数据生产和用户服务及运行提供数据层的支撑.介绍了科学应用系统的数据库架构设计、数据库的选择以及数据库性能优化和表样例.这里的数据库包括观测计划、工程参数、运维日志、科学数据、定标数据和特征事件识别等数据库.这些数据库的建设将为ASO-S卫星工程科学应用系统的顺利运行提供数据支撑,也可以为未来其他科学卫星类似数据库的搭建提供参考和借鉴.

The Science Operations and Data Center(SODC)of the Advanced Spacebased Solar Observatory(ASO-S)satellite project connects the mission and users,and is responsible for the science operations,the data production,management,distribution,and archiving.SODC heavily relies on various databases with high stability and performance.This article introduces the function architecture and performance optimization of the databases in the frame of the SODC software via several examples with detailed realizations of the database tables.The proposed databases for detailed design include observation plan database,engineering parameters database,operation log database,science data database,calibration data database,and featured event identification database.This article can be a reference for establishing similar databases of other scientific satellite missions.
