The Research of PApriori Algrithm Based on OLAP

摘要：

　　In analysis of association rules based on OLAP,the application of Apriori algorithm may need to scan the database frequently and generate massive number of candidate itemsets because of the complex system.According to the weakness,the paper proposes PApriori algorithm based on pretreatment,which reduces the time of scanning database to once,while not directly generate candidate itemsets,raise the efficiency Analysis of association rules based on OLAP efficiently.
