Abstract
We describe examples of problems of semantic heterogeneity in databases due to “domain evolution”, as it occurs in both single- and multidatabase systems. These problems occur when the semantics of values of a particular domain change over time in ways that are not amenable to applying simple mappings between “old” and “new” values. The paper also proposes facilities and strategies for solving such problems.Keywords
