摘要
在关系数据库中单表、星型模式或雪花模式之上建立一个逻辑结构 ,把要分析的数据及相关属性抽象成主题、立方体、事实、维、维层次和度量等对象 ,相关的处理过程抽象成对象的行为 .并介绍利用XML文档存储多维数据模型对象的信息的方法及立方体的创建过程 .实现了多维数据模型的对象化 。
To establish a logical structure on single table,star schema,snowflake schema and fact constellation of relation databases,data and attributes are to be abstracted to subjects,cube,facts,dimensions,dimension levels,measures and so on.Data disposals should be transformed into actions of objects.This article introduces the method as to how to save the multi dimensional data with XML documents and construction procedure of cubes.Multi dimensions data model is transformed into objects,which benefits OLAP and data mining.
