| Abstract: | The paper first introduces basic theory about Sql Server 2008 business intelligence platform and decision tree technology,and then preprocessing on data source.Using decision tree technology in Sql Server 2008 Business Intelligence platform,and data mining extension language(DMX) language to create the decision tree model of CET-4 score analysis.The evaluation results show that the model has high reliability and classification accuracy by using classification matrix and mining enhance figure,meanwhile,these rules corresponding to the model can be used as important reference for management and reform of English teaching. |
| Keywords: | Sql Server 2008 business intelligence platform decision tree technology ETL process DMX language classification matrix mining enhance figure |
