  1. Data Sharing in the Hyperion Peer Database System Patricia Rodriguez-Gianolli Anastasios Kementsietsidis Maddalena Garzetti Iluju Kiringa Lei Jiang Mehedi Masud Renée J. Miller John Mylopoulos Univ. of Toronto – Univ. of Ottawa – Univ. of Edinburgh – Univ. of Trento VLDB 2005 – Trondheim, Norway

  2. Data-Sharing between Sources I want info forsunny destinations I have flight UA928 I have info for Airport codes • Establish associations between the schemas and vocabularies of different sources • Use these associations to translate query requests between the sources (note: users don’t care/know about remote identifiers)

  3. Highlights… • We introduce an architecture for a data-sharing data management system • We propose mechanisms called mapping tables and coordination rules to support data-sharing services in the system • We propose a query mechanism for data-sharing environments

  4. The Hyperion Project URL: http://www.cs.toronto.edu/db/hyperion/ Project objectives: To investigate the data management issues that are raised by the P2P data-sharing paradigm Basic (architectural) design principles: • No global (common) schemas/vocabularies/… • Each peer source manages its own data • Each peer source manages its own acquaintances.
