Análisis Teórico-Experimental de Criterios de Comparación de Esquemas Conceptuales Orientados a Objeto

Some systems have the need to compare object-oriented conceptual schemas; the comparison criteria used have a big influence on the result produced. In this work, a classification of object-oriented conceptual schemas comparison criteria is presented, based on the kind of the information used to compare (meta-information, population information, exact or statistical information, etc.). For each criterion, its main characteristics and strong and weak points are detailed and validated with some results from industrial conceptual schema comparisons. Final conclusions contrast the statistical results with the theoretical analysis previously done. The present work is part of a data migration tool under development by the Department of Computer Science and Information Systems of the Technical University of Valencia – Spain.
