Query Processing in a Traceable P2P Record Exchange Framework
As the spread of high-speed networks and the development of network technologies, P2P technologies are actively used today for information exchange in the network. While information exchange in a P2P network is quite flexible, there is an important problem—lack of reliability. Since we cannot know the details of how the data was obtained, it is hard to fully rely on it. To ensure the reliabilit...
متن کاملQuery Processing with Materialized Views in a Traceable P2P Record Exchange Framework
Materialized views which are derived from base relations and stored in the database are often used to speed up query processing. In this paper, we leverage them in a traceable peer-to-peer (P2P) record exchange framework which was proposed to ensure reliability among the exchanged data in P2P networks where duplicates and modifications of data occur independently in autonomous peers. In our pro...
متن کاملTraceable Peer-to-Peer Record Exchange
Peer-to-peer (P2P) technology allows us flexible information sharing and communications in a wide-spread network. Unlike the traditional client-server architecture, a P2P network enables a peer to publish information and share data with other peers without central server control. In such an environment, tracing how data is copied between peers and how data modifications are performed is not eas...
متن کاملA Query Reformulation Framework for P2P OLAP
The idea of collaborative business intelligence is to extend the decision-making process beyond the company boundaries thanks to cooperation and data sharing with other companies and organizations. In this direction, we propose a query reformulation framework based on a P2P network of heterogeneous peers, each exposing OLAP query answering functionalities aimed at sharing business information. ...
متن کامل"Pay-as-You-Go" Processing for Tracing Queries in a P2P Record Exchange System
In recent years, data provenance or lineage tracing has become an acute issue in the database research. Our target is the data provenance issue in peer-to-peer (P2P) networks where duplicates and modifications of data occur independently in autonomous peers. To ensure reliability among the exchanged data in P2P networks, we have proposed a reliable record exchange framework with tracing facilit...
