摘要
在浩翰的数据资源中发现并提取有价值的知识，是目前数据库研究的热点问题，为此，运用集合理论对关系数据库进行数据分类，抽取它们的共同特征，讨论了分类特征规则的基本模型，给出了发现算法；通过实例分析表明：该算法能够快速发现分类特征规则，具有现实意义．
It is an important problem in database reasearch field to find and extractive the valuableknowledge in the vast date asoures. This paper classifieds the data in relation database using set theory,extractives their common characteristic, proposes the basic model of classification-characteristic rules,and then gives its algorithm.The experiments show that the algorithm can discover the classification characteristic rules fast, and is more efficient and practical.
