SI-Designer: A Tool for Intelligent Integration of Information

SI-Designer (Source Integrator Designer) is a designer sup- port tool for semi automatic integration of heterogeneous sources schemata (relational, object and semi structured sources); it has been implemented within the MOMIS project and it carries out integration following a semantic approach which uses intelligent Description Logics-based techniques, clustering techniques and an extended ODMG-ODL lan- guage, , to represent schemata, extracted, integrated information. Starting from the sources' descrip- tions (local schemata) SI-Designer supports the designer in the creation of an integrated view of all the sources (global schema) which is expressed in the same language. We propose SI-Designer as a tool to build virtual catalogs in the E-Commerce environment.
