摘要
煤矿安全监控系统的数据将随时间推移成为海量数据,大大影响系统查询时的效率,甚至可能影响到系统的其它功能。面对这种情况,本文从数据库结构设计、数据库文件存储模式等角度提供了优化数据查询的几种思路。
The data of safety monitor and control system in coal mine would become mass data over time,which will greatly influence on system query efficiency and even influence other functions of the system.Aiming at this situation,the paper gives several ideas of optimizing data query from the angle of database structure design and database files storage mode.
