    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.

    In this paper, we outline our efficient sample- based approach to answer fixed-precision approximate continuous aggregate queries in peer-to-peer databases. We describe our approach in the context of Digest, a two-tier system we have developed for correct and efficient query answering by sampling. With Digest, at the top tier we develop a query evaluation engine that uses the samples collected ...
