摘要
基于完全分布的P2P架构对高维数据索引能够消除集中式系统瓶颈,提高系统的可扩展性、可靠性以及健壮性。本文对目前的P2P多维数据索引技术进行了论述,指出了其优势与不足。在其基础之上,提出了一种新的基于P2P的多维索引技术,该方法克服P2P架构的不足,能够很好的支持多维范围查询。
The technology of multi - dimension indexing which is based on decentralized P2P architecture eliminates the bottleneck of that based on centralized system and enhances the extensibility, rehability and robust. This paper addresses the technologies of multi - dimension indexing based on P2P and the merit and drawback of these technologies are pointed out. Furthermore, novel P2P architecture for multi - dimension indexing is proposed which can effectively support multi - dimension range query and makeup the drawback of trsditional P2P architecture.
