  • Fixed-Precision Approximate Continuous Aggregate

    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 ...

  • Aggregate Queries in Peer-to-Peer OLAP - CORE

    Abstract. 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.

The proposed scalable paradigm can be tuned through two parameters to trade off between system scalability and answer optimality.
