Overview
Data binding provides a way for developers to create a read/write link between the controls on a form and the data in their application (their data model). Classically, data binding was used within applications to take advantage of data stored in databases. Windows Forms data binding allows you to access data from databases as well as data in other structures, such as arrays and collections.

WSDL provides a way for service providers to describe the basic format of web service requests over different protocols or encodings. WSDL is used to describe what a web service can do, where it resides, and how to invoke it.

UDDI registries describe numerous aspects of web services, including the binding details of the service. WSDL fits into the subset of a UDDI service
XQuery is a query language (with some programming language features) that is designed to query collections of XML data. It is semantically similar to SQL.
XQuery 1.0 was developed by the XML Query working group of the W3C. The work was closely coordinated with the development of XSLT 2.0 by the XSL Working Group; the two groups shared responsibility for XPath 2.0, which is a subset of XQuery 1.0. XQuery 1.0 became a W3C Recommendation on January 23, 2007.
"The mission of the XML Query project is to provide flexible query facilities to extract data
