探讨了水文遥测系统采集的历史雨量、水位数据、研究水位和各分区雨量的关系,提出一种全新的解决方法,即决策分析方法中的联机分析处理(OLAP)法。介绍了OLAP的理论,通过实例详细阐述了在实际条件下OLAP各要素的构建、数据展示以及最终分析结果。该方法依据可靠的基础数据,分析历史数据,得出数据间的关系,可在拥有多年数据积累的领域如水文、水质、气象监测等部门推广应用。
This paper discusses the relationship between historical rainfall, water level data, research water level and rainfall of each subarea collected by hydrological telemetering system and puts forward a new solution method, namely online analytical processing (OLAP) method in decision analysis method. The theory of OLAP is introduced. The construction of OLAP, the data display and the final analysis results are described in detail through examples. Based on the reliable basic data, the method analyzes the historical data and obtains the relationship between the data, which can be popularized and applied in such fields as hydrology, water quality and meteorological monitoring that have accumulated many years of data.
