XQuery Update Facility

The XQuery Update Facility is an extension to XQuery, a language used for querying XML data. It enables users not only to retrieve information from XML documents but also to modify them—such as adding, deleting, or changing elements and attributes. This makes it possible to update XML data directly within the query language, streamlining data management processes. Essentially, it transforms XQuery from a read-only tool into a powerful system for both accessing and maintaining structured XML information efficiently.
