摘　　要：最近一段时间,由于许多Peer-to-Peer(简写为P2P)系统例如Napster、Freenet和Gnutella等的成功应用,P2P数据共享问题成为国际上应用领域和研究领域内的热点。在数据管理领域内的国际会议和杂志上也可以纷纷见到这方面的文章,分别从体系结构、数据表示、数据检索、资源管理和安全与法律等方面着手研究在P2P的环境下进行数据共享的问题。由于Peer-to-Peer自身开放性和松散性的特点,导致了P2P系统在很多方面都需要进行进一步的深入研究。在本文中,我们将对P2P数据管理领域内目前的研究现状作一个综述。Data-sharing in P2P has become a hot research topic as well as in application system, especially after its successful application on those popular P2P system such as Napster,Freenet and Gnutella etc. Researchers around the globe are trying to address potential P2P Data-sharing issues in respects of system architecture, data expression, data retrieval .resource management, security and rules. A lot of issues have been researched in great depth. Many papers and articles have been published in the international Data Management conferences and journals. However P2P system is an open and loose system by nature,there are still many problems need future study.This paper gives out our view on today's P2P research status in the field of Data Management System.
