航天器测控系统数据库特点及性能测试策略

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。

Features of Spacecraft TT&C System Databases and Performance Test Strategy

As spacecraft TTC systems involve a large amount of data and complex relationships,large-scale relational 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 TTC databases,this paper studies objective evaluation of the performance of such databases and puts forward a configurability strategy for test of database performance.
