00925njm 22002777a 4500 dc Mazumdar, Subhasish author 1993 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.
