Abstract Approximating Aggregation Queries in
Abstract Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large scale, ad-hoc analysis queries – e.g., aggregation queries – on these databases poses unique challenges. Exact solutions can be time consuming and

Robust and efficient aggregate query processing in peer-to ...
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.

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 ...

Second, we propose "Digest", a two-tier system for correct and efficient query answering by sampling. At the top tier, we develop a query evaluation engine that uses the samples collected from the peer-to-peer database to continually estimate the running result of the approximate continuous aggregate query with guaranteed precision.

Query Routing and Processing in Peer-To-Peer Data Sharing ...
Abstract. Sharing musical files via the Internet was the essential motivation of early P2P systems. Despite of the great success of the P2P file sharing systems, these systems support only "simple" queries. The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file.

May 23, 2008 Abstract: With the increasing popularity of the peer-to-peer (P2P) computing paradigm, many general range query schemes for distributed hash table (DHT)-based P2P systems have been proposed. Although those schemes can provide range query capability without modifying the underlying DHTs, they have the query delay depending on both the scale of the system and the size of the query space or the ...

Queries containing aggregate functions often combine multiple tables through join operations. We call these queries "aggregate-join" queries. In parallel processing of such queries, it must be decided which attribute to be used as a partitioning attribute, particularly join attribute or group-by attribute.
