XML Databases

Summary

XML databases provide an easy and powerful way to store your XML documents so they can be quickly searched later. The XML database follows a hierarchical storage structure analogous to the folder structures in your file system.

The XML documents stored in the database are organized into collections. You learned how to create collections, how to create subcollections, and how to delete collections and subcollections by using command-line utilities. You also learned how to add and remove documents to the collections by using command-line utilities.

In addition, you learned to perform all these activities through a program interface. You learned the XUpdate language syntax that allows you to write queries for updating the contents of the XML database.

Finally, you learned about database administration used to manage the database and its contents. You learned the techniques of backing up and restoring the database. You also learned to export the database content into its native format and to import the earlier exported content into the database again.
