XQuery Update Facility (XUQ)

The XQuery Update Facility (XQUF) is an extension to the XQuery language that enables users to modify XML data directly. It provides standardized commands for adding, deleting, or replacing parts of an XML document, making data management more efficient and consistent. Think of it as a specialized toolset that allows precise, structured updates to XML data stores, similar to editing a document with a set of clear and safe editing instructions. This helps developers maintain and manipulate XML data effectively within database systems or applications.
