Conference proceedings 2003e Web, there is a fast-growing interest in using XML as the standard exchange format for distributed query processing. As a result, many relational database systems export data as XML documents, import data from XML documents, provide query and update capabilities for XML data.

We illustrate how these equivalences can be applied successfully to unnest nested queries given in the XQuery language. Measurements illustrate the performance gains possible our approach.作者: congenial 時間: 2025-3-26 23:58
The Crisis of Physical Illness: An OverviewXPath expressions play a central role in querying for XML fragments.
