摘要
Apriori算法是挖掘关联规则的经典算法。在分析该算法的基础上,在实际项目应用当中,结合SQL的特点,提出Apriori算法在SQL中的改进算法——Apriori_Sql。应用Apriori_Sql算法只需扫描一遍数据库,在数据库临时表中建立原始数据库的压缩数据映射,实验表明该算法是一种高效的关联规则的挖掘算法。
Apriori algorithm is a classical algorithm of association rule mining. A new association rule algorithm, improved Apriori algorithm with SQL-Apriori Sql, is presented based on analysis Apriori algorithm. Apply Apriori_Sql algorithm only need one scan of database, building the compressed data mapping of original database in temp table, and practice results show that Apriori_Sql algorithm is an efficient algorithm.
