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

2 Data-Sharing between Sources I have info for Airport codes AirporCodes… YYZ… EZE… Flight No.… UA928… UA8853… I have flight UA928 UA928 I want info for sunny destinations Destinations… Edinburgh… Toronto… Establish associations between the schemas and vocabularies of different sources 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) 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 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 mechanisms called mapping tables and coordination rules to support data-sharing services in the system We propose a query mechanism for data-sharing environments We propose a query mechanism for data-sharing environments

Each peer source manages its own acquaintances. The Hyperion Project
