Building XML Documents and Schemas to Support Object Data Exchange and Communication

The exchange of data between heterogeneous database systems is becoming a key issue in several application domains. XML is emerging as the standard mean for data exchange over the web. As for object oriented databases storing complex information, it is important to be able to exchange both objects and object schemas. In this paper we propose two approaches for translating database objects into XML documents which are both human readable and suitable for system based queries, thus preserving object semantics. Both approaches have been validated by a running prototype.
