Abstract

This paper presents a query translation mechanism between heterogeneous peers in Peer to Peer Database Sharing Systems (PDSSs). A PDSS combines a database management system with P2P functionalities. The local databases on peers are called peer databases. In a PDSS, each peer chooses its own data model and schema and maintains data independently without any global coordinator. One of the problems in such a system is translating queries between peers, taking into account both the schema and data heterogeneity. Query translation is the problem of rewriting a query posed in terms of one peer schema to a query in terms of another peer schema. This paper proposes a query translation mechanism between peers where peers are acquainted in data sharing systems through data-level mappings for sharing data.
