This article explains how DynCorp (CSC) used XQuery at NASA's Johnson Space Center to Simplify XML Data Access and Integration in a real-world data integration application. Michael Ritchson is a systems integrator employed with a DynCorp (recently bought out by CSC), who is the present contractor for NASA's Aircraft Operations in Houston, Texas. His duties include Architecting and developing JAVA J2EE web applications for their managers, team leaders, and employees, which vary from Quality Document routing systems to CRM tools. This article describes Michael's XQuery experiences, in his own words.

"Learn XQuery in 10 Minutes" is the perfect XQuery primer for all those people who really want to know what XQuery is, but don't have the time to find out. We all know the problem: so many exciting new technologies, so little time to research them. So, we've packed all the XQuery essentials into a brief primer covering the following topics: * What is XQuery for? * Building Your First XQuery * Accessing XML Documents with XQuery * XQuery FLWOR expressions * Generating XML output with XQuery * Understanding the Relationship between XQuery and Databases Read the new XQuery Primer at: http://www.stylusstudio.com/xquery_primer.html

XQuery shows much promise for software architects and developers because it greatly reduces the amount of code you need to write to build services that work with XML. You might think XQuery does everything and is well understood, but misconceptions and misunderstandings still exist in the software development community about XQuery. In this IBM Developerworks article, Frank Cohen details and clarifies many of the myths and misunderstandings that surround XQuery.

Learn the basics of the XML query language with this tutorial by XML expert Jonathan Robie. Jonathan is XML Program Manager at DataDirect Technologies, an editor of several of the XQuery specifications, and a well-known speaker at XML conferences. The tutorial presents the XQuery language in detail using a series of queries that illustrate both the mechanics of the language and the rationale for the features of XQuery. It is excerpted from the recent book that Jonathan collaborated on called "XQuery from the Experts - A Guide to the W3C XML Query Language." Free printable PDF download!

The two chatted about what's the scoop on Microsoft and XQuery technologies - Read on!

An interview with Dr. Daniela Florescu, one of the editors of the standard XML Query Language, XQuery. She has been involved with the XML Query Working in W3C group since its inception, and she authored two XQuery precursors, XML-QL and Quilt. Today, Dr. Florescu represents Oracle Corporation in the Working Group. Inside Oracle, she is helping the XQuery team develop their products in Oracle10g. Prior to Oracle, Daniela was founder and CTO of XQRL, a startup whose goal was to build a streaming XQuery engine. This article talks about her research project familiar to most in the XML community — trying to extend XQuery to a full programming language for Web services!
