SI-Designer: a tool for intelligent integration of information

SI-Designer (Source Integrator Designer) is a designer support 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 language, ODL(I/sup 3/), to represent schemata, extracted, integrated information. Starting from the sources' ODL(I/sup 3/) descriptions (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 ODL(I/sup 3/) language. We propose SI-Designer as a tool to build virtual catalogs in the e-commerce environment.
