In this paper, we outline our efficient sample based approach to answer fixedprecision approximate continuous aggregate queries in peertopeer databases. We describe our approach in the context of Digest, a twotier 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

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 clientserver models, no central coordination exists in a P2P system thus, there is no central point of failure. P2P

Then, to improve system scalability of processing continuous privacyaware queries, we propose a shared execution paradigm that shares query processing among a large number of continuous queries. The proposed scalable paradigm can be tuned through two parameters to trade off between system scalability and answer optimality.
