CiteSeerX — Aggregate Queries in Peer-to-Peer OLAP

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A peer-to-peer (P2P) data management system consists essentially of a network of peer systems, each maintaining full autonomy over its own data resources. Data exchange between peers occurs when one of them, in the role of a local peer, needs data available in other nodes, denoted the acquaintances of the local peer.
