This paper describes a metadata interchange approach for semi-automated integration of heterogeneous distributed databases. Our system prototype uses distributed metadata to generate a GUI tool for a meta-user (who does the metadata integration) to describe mappings between master and local databases by assigning index numbers and specifying conversion(More)
Peer-to-peer computing is a term used to describe the current trend toward utilizing the full resources available within a widely distributed network of nodes with increasing computational power. These resources include the exchange of information, processing cycles, cache storage, and disk storage for files. Routing, locating and transmitting of resources,(More)
Experience suggests that fully automated schema matching is infeasible, especially when n-to-m matches involving semantic functions are required. It is therefore advisable for a matching algorithm not only to do as much as possible automatically, but also to accurately identify positions where user input is necessary. Our matching algorithm combines several(More)
