基于OLAP技术的污染源在线监测数据分析系统

OLAP-based on-line monitoring and data analysis system of pollutant source

污染源在线监测数据分析系统基于污染源管理综合系统数据库提供的数据源,经过数据清洗、转换,加载到数据仓库中,进行主题设计与多维建模,采用OLAP技术实现海量数据展示、分析统计,同时提供功能强大的共享查询、多维分析和污染源企业排口监测因子预警、事件自动提醒及各类数据报表统计等,提高了减排工作信息化的水平和工作效率。

The datasource of on-line monitoring and data analysis system of pollutant source is based on integrated pollutant management system database. After data cleaning, transformation, the data is loaded into the data warehouse. Thematic design and multi-dimensional modeling, mass data show using OLAP technology, statistical analysis, a powerful shared inquiry, multi-dimen- sional analysis and the notice and alarm of monitoring emission factor from enterprise pollutant source, automatic event reminders, various data statistical reports are provided, It also improves the information level of emission reduction and working efficiency.
