数据仓库主题的M_d距离测度搜索算法

An M_d Distance Measure Algorithm for Searching Themes of Data Warehouse

分析了数据仓库主题的特征,给出了选择准则,提出了一种基于Md测度的主题搜索算法。该算法以数据仓库主题特征矢量空间中的距离为测度,从关系数据库中寻找具有数据仓库主题特征对象。还对该算法的计算复杂性进行了说明,并给出了一个SQL平台上的应用实例。

First describe some specific theme features of data warehouse and present an evaluation rule.Next,for the purpose of searching the objects in the database with theme features, we propose a M d-based algorithm using the distance measurement defined in a theme eigenvector space. And the complexity issues of the algorithm are also mentioned. Finally,Implement this algorithm on a SQL platform.
