| 摘 要： | 1 前言随着人们生成、收集和存储数字化数据能力的极大提高,当今世界面临着各种原始数据的爆炸性增长。数据库技术的巨大进步创建了对大量数据的有效存储,成千上万的大型数据库被广泛地应用在商业、政府和科研等等部门。大量数据资源的积累为人们从历史数据中发现有用信息提供了基础,人们期望数据库能够提供智能化或者至少是半自动化的数据分析处理的能力。于是,数据仓库技术(Data Warehouse)、联机分析处理技术(On Line Analysis Processing)以及数据挖掘技术(Data Mining)应运而生。

| Abstract: | With the rapid development of data warehouse and OLAP techniques, the researchers begin to pay attention to the data mining in the data cube. Recently, Dr. T. Imielinski etc. firstly presented the problem of the cube gradient mining that is a generalization of association rule in data cube. In this paper, we firstly introduce the related concepts of data cube and condensed cube with an emphasis. Then we introduce some interesting problems related to the cube gradient mining including: constrained cube gradient mining and the query language of cube gradient. Finally , we introduce several issues on the combination of cube gradient and the condensed cube, that is, the cube gradient mining in the materialized data cube and the integration of cube gradient mining and cube browse. |
