摘要
传统的数据库管理系统存储性能无法满足高达20 M b/s的采样数据存储速度要求。建立了一个三层文件系统,将一天的采样数据按照通道号、采样开始时间分层存储,并对每层数据提供相关的索引文件,既满足了采样数据存储速度要求,又提供了简单的按通道数、按时间段的快速查询服务,对相似系统的设计与实现具有借鉴意义。
The velocity of sample data storiage can＇t satisfy the demand ot 20 Mbytes per second by using traditional DBMS. Therefore, a 3-layer file system is established. The sample data in one day are divided into several layers based on the channel number and the beginning time of sampling. The index documents are provided for querying data in every layer. Consequently the demand of storing velocity is satisfied and the sample data can be queried by providing the channel number and the time of sampling. Finally this system will provide a reference for the design and implementation of other similar systems.
