In this work, we investigate mechanisms to support data sharing and querying in a peer-to-peer data management system, that is, a peer-to-peer system where each peer manages its own data To support data sharing, we propose the use of mapping tables which list pairs of corresponding data values that reside in different peers Our work illustrates how automated tools can help manage the tables between multiple peers by inferring new tables from existing ones and by checking their consistency In terms of querying, we propose a framework in which users pose queries only with respect to their local peer Then, we provide a rewriting mechanism that uses mapping tables to translate a locally expressed query to a set of queries over the acquainted peers.
