摘要
该文首先对决策树技术相关理论和SQL Server2008 BI平台作了介绍，然后对用于挖掘分析的数据源进行了预处理。利用SQL Server2008BI平台下的决策树分类技术和DMX语言即数据挖掘扩展语言创建了课程成绩分析决策树模型。挖掘提升图和分类矩阵对该模型的评估结果表明模型具有较高的可靠性和分类准确度，同时模型对应的一些规则和模式可作为课程教学管理及改革的重要参考依据。
The paper first introduces basic theory about decision tree technology and SQL Server 2008 BI platform and,and then prepro- cessing on data source for mining analysis.Using decision tree classifying technology in SQL Server 2008 BI platform,and DMX language , namely data mining extension language,to create the decision tree model of course score analysis,The evaluation results show that the model has high reliability and classification accuracy by mining enhance figure and classification matrix, meanwhile,these rules corresponding to the model can be used as important reference for management and reform of course teaching.
