The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools. A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis. Unlike traditional client-server models, no central coordination exists in a P2P system; thus, there is no central point of failure.
