摘要
在文献 [1 ]的基础上 ,利用关系数据库本身的关系操作 ,把关联规则的提取扩展到整个数据库的具有关系互联的多表中 ,从而解决在关系数据库实际应用中需要多个数据表同时配合进行数据挖掘。在多表关联中 ,采用了标准关系数据库的关系操作 ,且运用单表的快速关联规则提取算法 。
A fast associated regulation arithmetic is brought forward in this paper, which can be retrieved associated regulation fast from multi-table in relation database. The arithmetic works with 3NF formula of relation database. For SQL language is used, the arithmetic can accord with any relation databases. The standard relation operation is used on multi-table, the associated regulations are retrieved fast as it is retrieved from single table.
