XML databases like Mark Logic and eXist are aware of the structure of the XML content stored within the database. This makes it easier and faster to do queries based on the underlying structure of the data then would be possible in a purely relational system.

This is especially useful when the input to the system and the output to the system are both XML (such as web content management). In those cases, storing the binary XML content in an XML database removes the need for transforming the content into rows in a database and then back into XML while preserving the ability to query based on specific XML properties.
