Peer-to-peer computing consists of an open-ended network of distributed computational peers, where each peer can exchange data and/or services with a set of other peers. The Peer-to-peer computing paradigm is characterized by the lack of global control in the form of global registries, global services, global resource management, or global schema and data repository. Systems such as Napster and Gnutella popularized the P2P paradigm as a version of distributed computing lying between traditional distributed systems and the web.
The objective of the Hyperion Project is to investigate the data management issues that are raised by this paradigm in scenarios where each peer may have data to share with other peers. We highlight some of the main goals of the project which are: the precise definition of a peer-to-peer data management architecture; the study of viable data integration/exchange/mapping mechanisms for such a dynamic, autonomous environment; the development of algorithms for the efficient search, retrieval and exchange of data among the peers.
