A Publish/Subscribe Scheme for Peer-to-Peer Database Networks

Speaker: Dr Jian Yang, InfoLab, Tilburg University

When: 02.00PM, Thursday 18 Sep 2003

Venue: 78-420

Host: Ralph Muhlberger

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.
