水质数据计算机管理系统分析

水质数据计算机管理系统是用计算机来处理水质数据，完成从原始的计算、分析、统计、斩汇编、水质评价一直到数据存贮入库，绘制污染状况图等一系列工作，既提高了水质数据的可信度，又缩短了水质数据采集，服务的周期。系统通过对大量用记需求信息的归纳，提出了符合水质数据规律的概念模型，采用分层技术进行系统分析，使整个系统功能齐合，用户界面友好，操作方式灵活，输出内容丰富，并可在ＶＡＸ系列计算机入ＩＢＭ系列微机上运

Analysis of Computer Management System of Water Quality Data

The computer management system of water quality data is used to deal with the water quality data.In the system,the computation and analysis and comprehensive compilation of firsthand data,water quality as-sessment, data storing as well as pollution status map drawing can be made with the computers, The system hasnot only improved the reliability of water quality data,but also shortened the period trom data collection to pro-viding service. Considering the users'requirements for information,the concept model which follows the waterquality data law is established in the system Svstem analysis by means of hierarchy technic enables whole system to have full functions,user-friendly interface,easy operation and many kinds of outputs Furthermore.it can be run both on the VAX mini computers and IBM compatible micro computers. It has a strong applicability.
