A Peer to Peer Database Model Based on Chord

A local relation model of database which is based on chord in peer to peer systems is proposed in order to solve the problems that bottleneck node and higher network transfer load for keeping the data consistency between nodes are in distributed database system based on client/server. Node catalog system in application layer is built on overlay so that the distributed search in P2P application system is realized effectively. By instance analyzes, distributed storage and resource location are resolved, at the same time, high scalable, lower communication, more flexible sharing on data and service and better reliability are proved to be the attributes of the LRM based on Chord.
