Trend of P2P Data Management
P2P数据管理研究趋势

Peer-to-Peer is a new model of architecture,which has a lot of advantages to be further discovered and has a cheerful application future.Firstly,the paper points out that the schema-based highly scalable P2P system can satisfy the needs for both semantic support and high scalability in P2P research area,and so it is the trend of P2P data management.Then,through the survey on the current schema-based P2P systems and the highly scalable P2P systems,the paper points out that the current P2P data management research projects improve the efficiency and quality of service of the existing P2P network from two(facets:) the semantic overlay and the overlay,and the lack of connection between them makes it too difficult to generate the schema-based highly scalable P2P system from them.After that,the goals of the schema-based highly scalable P2P system are given,and the initial result of this research area is analyzed.Finally the issues which need to be further studied are pointed out.
