Abstract: This paper studies data generalization method of database with the rough sets theory, and proposes a data generalization algorithm based on rough sets. It can be used to reduce the attributes from database and generalize the data with concept hierarchies tree.

摘要： 应用粗糙集理论对大型数据库中的数据概化进行了研究，提出了对数据的动态概念层次划分算法，用以对相关数据集进行属性约简，并在此基础上挖掘概化特征，动态维护概念层次树。
