Abstract

Abstract: A peer-to-peer（P2P） OLAP network system consists of OLAP servers which maintaining full autonomy over its own data resources.When data exchange between OLAP servers occurs，how to mapping the pattern of different of data cube in order to execute union OLAP query is become a key issue.This article provides a mapping rule based on Dimension Hierarchical Chain（DHC） which has been defined before.This rule can produce a global optimum execute plan about union OLAP query.

Key words: OLAP, data cube, P2P network, Dimension Hierarchical Chain

摘要： P2P网络环境下，每个OLAP服务器上都有一套完整的数据解决方案。当OLAP服务器之间进行协同工作时，如何将Data Cube中的模式进行匹配以完成联合OLAP查询成为一个关键问题。在对Data Cube中的维及维层次链进行了定义后，提出了一种维层次链的匹配规则，能较好地优化P2P网络环境下执行联合OLAP查询。
