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)
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
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.
