XQuery processing in oracle XMLDB," Proc.
In particular, the idea of mining association rules [1] to provide summarized representations of XML documents has been investigated in many proposals either by using languages (e.g.,
XQuery [2]) and techniques developed in the XML context, or by implementing graph-or-tree-based algorithms.

XQuery is a query language that is designed to query collections of structured and semi-structured data
Designed to meet the data transformation and aggregation needs of developers, the DataDirect Data Integration Suite contains the latest product releases of DataDirect
XQuery [R], DataDirect XML Converters[R] (Java [TM] and NET) and Stylus Studio[R] in one simple, highly flexible and robust installation.
Many SQL-based DBMSs now support storing of XML data, as well as querying XML data directly using a query language such as
XQuery.
XML programmers and database users will find Priscilla Walmsley's
XQUERY (0596006349, $49.99) a specific, valuable reference which is based on the
Xquery 1.0 standards and which offers a basic tutorial on specifications and programming with the query language base.
Because XPath complexity influences the complexity of query expressions (
XQuery (25)) required to target document sections and data elements, these results suggest that searching XML document collections would be simpler and less prone to error with CLP-ML than CDA markup.
list-price = SELECT price * (1 + fee-rate) FROM HOUSES, AGENTS WHERE agent - id = id In general, a variety of approaches have been used to specify semantic mappings (for example, SQL,
XQuery, GAV, LAV, and GLAV [Lenzerini 2002]).
