How RLPTechnologies Used XQuery to Process Huge XML Files

Dear XML Developer,

It's official. The XQuery 1.0 specification is now a W3C Recommendation. And XQuery is already hard at work in real world, commercial applications. Here's what Clara Sagan, a Senior Product Engineer at RLPTechnologies, had to say about how they're using XQuery, and why:

"To meet the product requirements for OneView360°, we needed to process XML files of up to 50GB successfully 100% of the time in an efficient manner. DataDirect's optimization techniques, including Document Projection and Document Streaming, allowed us to meet our requirements and clearly positioned DataDirect XQuery™ 2.0 ahead of its competitors"

Read more about how RLPTechnologies takes advantage of the power of XQuery using DataDirect XQuery later in this newsletter. If scalable XML processing is important to you and your application, this is one story you don't want to miss.

Also this month, we've got several new articles and resources, including Understanding the Importance of XQuery to SOA, and news on upcoming user groups where you can learn about using XQuery to integrate and process relational and Web services data – all this and more in this month's issue of the DataDirect XQuery eXtra.

Sincerely,
Nancy Vodicka
Product Manager, DataDirect XQuery

1. How RLPTechnologies Uses XQuery to Process Huge XML Files

Leading software development organizations are already leveraging XQuery to realize massive performance advantages in XML document processing for their commercial applications. Here's what Joe LaFeir, vice president of product development at RLPTechnologies had to say about his experience using XQuery:

"DataDirect XQuery™ 2.0 provided a commercial, well-supported implementation of the XQuery specification while delivering the performance, scalability and reliability necessary for our large scale XML profiling needs. Using the DataDirect XQuery has helped us significantly reduce our development effort, which helped bring our OneView360° Data Quality Inspection module to market faster."

Read about RLPTechnology's application requirements, their evaluation criteria, why they chose DataDirect XQuery 2.0, and the benefits they realized in this DataDirect XQuery customer profile.

2. XQuery 1.0 is now an Official W3C Recommendation

XQuery 1.0 became an official W3C Recommendation on January 23, 2007, and it is already widely implemented in industrial-strength applications, including applications for XML processing and data integration.

But not all XQuery implementations are created equal. DataDirect XQuery excels at performance, scalability, stability, and it's easily embedded and standards compliant. DataDirect XQuery is a well supported, robust, commercial XQuery implementation for XML that works for very large XML files (+50GB), relational databases, EDI and other legacy data sources, and more. To get started with XQuery, download DataDirect XQuery today.

3. Understanding the Importance of XQuery for SOA

A new article entitled XQuery is Key to SOA Implementation has been published and argues that enterprises should give careful attention to their data when designing a service-oriented architecture (SOA). Key criteria for successful SOA implementations include the ability to efficiently process XML, and the ability to easily incorporate data from a variety of sources, processing them together with data from incoming requests to create responses. XQuery can dramatically simplify SOAs, increasing programmer productivity and improving performance, and XQuery can be used to define general data services that can be used throughout the enterprise. Using XQuery for XML processing, data integration, and data services will simplify your programs, increase programmer productivity, and improve the performance of your systems. Read the article online today.

4. Join Us on March 21 at the Washington DC XML Users Group

Join Minollo, DataDirect's Sr. Program Manager for XML Technologies, for a talk entitled Using XQuery to process and integrate XML, relational, Web services, and legacy data. This session provides an overview of the XQuery language, how XQuery can be leveraged in complex data integration scenarios, and how XQuery can easily fit into various architectures, including today's SOAs. Live demos will provide hands-on experience about the power and flexibility of the XQuery language.

By attending the session, you will have answers to these and other questions:

• Can I use XQuery to query large XML documents?
• Can I use XQuery to query non-XML documents?
• Why would I use XQuery instead of Java?
• How do I get started with XQuery?
• How can I modularize my XQuery?
• How is XQuery different from XSLT?

Event Details: Wednesday March 21, 2007 at 7:00PM. Held at the American Geophysical Union, 2000 Florida Avenue NW (near Dupont Circle). Visit the DC XML User Group for more information.
