A deductive approach to semantic heterogeneity in multidatabase systems Mazumdar, Subhasish Information storage and retrieval systems Management information systems Deductive databases Sistemes d'informació per a la gestió Bases de dades Bases de dades deductives Informació -- Sistemes d'emmagatzematge i recuperació Heterogeneous Databases are becoming increasingly important, but they present several problems. We consider the problem of semantic heterogeneity and show that a deductive model is suita.ble for coping with the problem. This deductive da.ta.base resolves sema.ntic connections a.mong symbols in loosely coupled da.ta.bases a.nd al­ lows multida.ta.bases to a.ccess data. from them. We also d.iscuss ways of detecting semantic heterogeneity a.nd d.iscrepancies. 1993 Conference report http://creativecommons.org/licenses/by-nc-nd/4.0/ Open Access Attribution-NonCommercial-NoDerivatives 4.0 International Universitat Politècnica de Catalunya.
