A schema analysis and reconciliation tool environment for heterogeneous databases

To support the development of uniform query interfaces over distributed and heterogeneous databases, tools for the analysis and reconciliation of database conceptual schemas are required. The paper presents the ARTEMIS tool environment developed to support the analyst in the process of analyzing and reconciling sets of heterogeneous data schemas. Schema analysis in ARTEMIS is performed according to the concept of affinity, while schema reconciliation is performed interactively on clusters of elements with affinity, based on unification rules. Issues on expected tool interaction and on experimentation and applicability of ARTEMIS are discussed
