中文摘要：
针对大型数据库挖掘中需要多次访问数据库和效率较低的局限性,提出一次性数据库访问策略,设计了基于Apriori的Apriori_ADO算法.经过实验分析,Apriori_ADO算法降低了算法的时间和空间开销,提高了关联规则挖掘效率.算法具有很强的实用性,已用于超市中顾客消费知识的挖掘,并取得了满意的结果.
英文摘要：
This article analyzes the Apriori algorithm,and points out the limitations that it requires many accesses in the large-scale database mining and its efficiency is low.Based on the strategy accessing to DB once,it designs Apriori_ADO algorithm based on the Apriori.This algorithm avoids cutting frequently.Experimental analysis shows that the new improved Apriori_ADO algorithm reduces the time and space,and improves the mining efficiency of association rules.Apriori_ADO algorithm has strong practicality;it has been used for supermarkets in customer consumer knowledge mining,and has achieved satisfying results.
