""The individual perspectives on the concepts behind the XQuery language offered by XQuery from the Experts "will be of great value to those who are seeking to understand the implications, opportunities, and challenges of XQuery as they design future information systems based on XML." --Michael Champion, Advisory Research and Development Specialist, Software AG XQuery answers the growing need for a functional XML search and transformation standard. Backed by the full weight of the World Wide Web Consortium (W3C), XQuery is being extremely well received by the IT community worldwide. The first major XML language that takes advantage of the benefits of strong typing provided by XML Schema, XQuery has the versatility to manipulate both XML and non-XML data and provides a valuable connection between the world of XML and relational databases. In "XQuery from the Experts, select members of the W3C's XML Query working group come together to discuss every facet of XQuery. From Jonathan Robie's introductory "XQuery: A Guided Tour" to Mary Mary Fernandez, Jerome Simeon, and Philip Wadler's "Introduction to the Formal Semantics," XQuery is revealed in a way that both novice programmers and industry experts can appreciate. Edited by long-time XML expert and programmer Howard Katz, coverage ranges from strictly technical chapters to comparative essays such as Michael Kay's "XQuery, XPath, and XSLT," which explores the common ancestry of all three languages, and Don Chamberlin's "Influences on the Design of XQuery," which details the process behind XQuery's design.

From corporate IT departments to academic institutions, XML has become the language of choice for storing and transmitting data across diverse application domains. For those new to the XML query language, XQuery, this example-rich text serves as a tutorial that brings readers quickly up to speed on XQuery's data model, type system, and core language features.

XQuery - 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.

Information retrieval query language - An information retrieval query language is a query language used to make queries into database, where the semantics of the query are defined not by a precise rendering of a formal syntax, but by an interpretation of the most suitable results of the query.

XML transformation language - An XML transformation language is a computer language designed specifically to transform an input XML document into an output XML document which satisfies some specific goal.

Database query language - Database query languages are like programming languages. The person formulating the query is expected to understand the relevant rules for formulating the query, and to program the query according to the requirements.
