n South African Computer Journal - Mapster : a peer-to-Peer data sharing environment




This paper describes a system called Mapster that allows users in a P2P network to share their databases. The research addresses problems of heterogeneity and scalability in P2P databases. To provide fine-grained access to users' databases, schema matching and a super-peer topology are used. The schema matching component allows information to be translated by semi-automatically determining the mappings between the databases within the P2P network. A super-peer topology enables the schema matching techniques to operate effectively in large, dynamic, heterogeneous networks.
