Discussion and research of P2P Technology Applied in Distributed Database

This paper presents the concepts as follows: the smooth read of data could be ensured while the failure appears on the P2P-based network; based on data security,the data redundancy concept is proposed,including the local installations of multiple backup database servers,thus while the main server is failed,the backup data could be used. The servers are also set up in different places. When the distributed system is proposed,the distributed database appears,thus only the data integrity in the database server side could be guaranteed. However,there is no such guarantee for the client that once there is some problem in the connection with the host,the distributed database could not give full play to its own advantages. Now,by integrating P2P technology with the distributed database technology,the problems of distributed database network and database could be successfully solved.
