As to this research issue, the work in [8] introduces range semantics as the semantics of aggregate queries in the context of inconsistent databases. Range semantics is a form of certain answers semantics for aggregate queries and it guarantees that, in every possible world, the value of the aggregate query will be in a given interval. Ref.

Abstract. Peer-to-peer networks are considered the new generation of distributed databases, termed peer-to-peer databases. ... We complement these operations at the bottom tier by a set of approximate query processing techniques at the top tier to develop a two-tier system for answering both set-valued and aggregate queries in peer-to-peer ...
In this paper we present an unstructured peer-to-peer approach to aggregate node selection for resource management. Our objective is to efficiently calculate the aggregate value and search the aggregate node whose attribute matches or falls in the proximity of this value. ... Our contribution also includes the inclusion of an explicit network ...
Abstract: In this paper, we propose an efficient sample-based approach to answer fixed-precision approximate continuous aggregate queries in peer-to-peer databases. First, we …
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 …

A peer-to-peer (P2P) data management system consists essentially in 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.
Abstract—Peer-to-peer (P2P) databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering …
