一种基于倒排索引的海量工况数据库方案

The database solutions for dealing with mass work state data based on reverse index

文章介绍了一种通过在内存中对设备编号聚集数据并生成倒排索引的方案,从而使工况数据按应用需求以有序的方式存放在内存及磁盘中,实现在工程机械远程监控系统中对海量工况数据的快速写入及快速查询。

This paper describes a program that gathers data on the device number and generates inverted index.By buffering data in memory and clustering them with same equipment number,the work state data can be stored in disk orderly and be accessed quickly.
