McObject has released an XML interface for its eXtremeDB in-memory database system. The eXtremeDB XML interface enables data exchange between eXtremeDB and other XML-enabled systems, and provides a simplified means for updating underlying database structures. McObject has created a freely downloadable example program demonstrating the integration of the eXtremeDB embedded XML interface and Web Services through SOAP interfaces. eXtremeDB XML supports the W3C XML specification but stores its contents in the eXtremeDB binary format, applying eXtremeDB’s efficient in-memory storage methodology to the imported data. Stored objects retain eXtremeDB’s compact layout, as well as its fast and predictable search methods and updates. With eXtremeDB XML, the database still reads and writes XML in the context of transactions.
