Several federated database systems have been built in the past using the relational or the object model as federating model. This paper gives an overview of the XMLMedia system, a federated database system mediator using XML as federating model, built in the Esprit Project MIRO-Web. The system is composed of four main components: a wrapper generator using rule-based scripting to produce XML data from various source formats, a mediator querying and integrating relational and XML sources, an XML DBMS extender supporting XML on top of relational DBMSs, and client tools including a Java API and an XML query browser. The results demonstrate the ability of XML with an associated query language (we use XML-QL) to federate various data sources on the Internet or on Intranets.Read the full paper here: https://link.springer.com/chapter/10.1007/3-540-47866-3_34
