Abstract:Peer-oriented computing is a natural way for meeting the data
sharing requirements of decentralized, highly dynamic, scalable
applications. Peer-to-peer database solutions seek to share data and
link applications that might otherwise be incompatible. Data
sources are loosely coupled in peer groups where each peer performs
a dual role: it can be both a client that processes queries and a
server that provides data upon request.
In this seminar we present a framework for data sharing in a
peer-to-peer database network. We first introduce a
publish/subscribe model where peer groups are formed by matching
peer interests (subscriptions) against publications published by
relevant peers in the network. We show that queries can be processed
on basis of peer collaboration without the need for a global
schema. Moreover, we explain that a peer-to-peer database network
exhibits dynamic and scalable behaviour as peers can join and leave
the network at their own discretion.
