摘要
过程数据是一种丰富的信息资源,过程数据存储的主要目的是为了满足某些应用软件(如趋势图软件)对实时数据的需求以及用户对历史数据的查询。在福大自动化公司开发的实时数据库软件基础上,主要介绍以内存数据库和磁盘历史数据库来存储实时历史数据,重点研究过程数据的存储设计和存储结构。最后,由工程实例给出了存储系统的功能应用。
Process data is one kind of rich information resources,process data memory major objective is the need to real-time data and the consumer inquiry to history data for satisfying some application software.The basis is upper in Real -time database software developed in FDAUTO Company.This paper mainly introduces to store real and history data with memory database and disc history database,priority studies process data memory designs and storage structure.Finally,apply by the fact that the example has given out storage system.
