| With the increasing power demand, the rapid development of electric powerinformation network, the information management system can provide a higher levelof analysis demand increasing. The application of data warehouse technology makeup the information management system of decision-making support function. Basedon this, this paper is based on the electric power marketing business process, continueto provide quality services to customers the purpose, make full use of the datawarehouse technology advantage, through data mining tools, based on the existingmanagement information system, construction of power marketing decision supportsystem, so that the leadership of electric power enterprise decision is more convenient,scientific, accurate.First of all, through OLAP of data warehouse technology section,multi-dimensional data to cut, drill, rotate to realize data all-round, multi angle,observation and analysis of multi level; then, combined with the power marketingbusiness process, carries on the division to the theme of the power marketing datawarehouse, designed the electricity billing, Business News charging, electric energymetering, contract management, with seven different themes for electric inspection,quality of service and complaint, report, consulting, repair, installation conditions,preliminary build a conceptual model of the power marketing data warehouse:multidimensional data model, star or snowflake model; third according to the need ofelectricity market decision-making, the analysis of the discrete data, determine theelectric power marketing decision system adopted by the algorithm: Apriori algorithmand decision tree algorithm; finally, the online data warehouse analysis processingtechnique based on OLAP construct power marketing decision support system, thedesign of the data of electric power marketing decision support system conversionpolymerization system, query system, implementation of data conversion andmultidimensional preview. |
