Research on P2P database management system
基于P2P的数据库管理系统研究*

The traditional large-scale database system is a typical C/S structure.There are server nodes and a central server in the system.The large database system is running on the server.The nodes access the database through the server.But the C/S structure easily produces the system bottleneck on the server.To solve this problem,this paper introduced the peer-to-peer concept into database management system.Built a new system which had the benefit of the C/S model and peer-to-peer model at the same time.In this system,the relation between server and the clients was C/S mode.And all the clients form a peer-to-peer system.In order to improve system efficiency,this peer-to-peer system was split into several small peer-to-peer networks according to their visiting tables.Through the approach, achieved the cache data sharing between the clients,reduced the frequency to visits to the server.lightened the burden of the server,and reduced the possibility of system bottleneck.So the system is a beneficial experiment to combine the benefit of C/S mode and peer-to-peer model.
