Abstract

Networked environments like the Internet have catalyzed a phenomenal growth in the publication if data bringing with it an increasing need to share and integrate information. Alas, the format of data to be inegrated varies from company to company and sometimes from person to person. To accomplish tasks shuch as data sharing, exchange, and integration, we may need to map an XML schema to a relational scema to drive trasformation of XML elements into relational data or map an XML scema of one application to that of another, or query posed against a high-level semantic model may need to be mapped into an equvalent query posed against a logical database schema.
