航天器测控系统数据库特点及性能测试策略

摘要

航天器测控系统的数据量大,信息关联复杂,一般都用大型的关系数据库作为其数据存储与管理的基础平台.存储系统建成后,数据库性能究竟如何,数据库性能该如何衡量,这一直是系统集成者和应用者关心的课题.本文从测控数据库的特点出发,客观分析了数据库实际运行性能,提出了一种较为全面的航天器测控系统数据库的性能测试策略.%As spacecraft TT&C systems involve a large amount of data and complex relationships, large-scale rela tional databases are usually used as the data storage and management platform. Following building of a data storage system, issues of lasting concern to system integrators and users include: What is the performance of the database? How to evaluate the performance of the database? Based on the characteristics of TT&C databases, this paper stud ies objective evaluation of the performance of such databases and puts forward a configurability strategy for test of database performance.
