Processing Very Large XML Files with DataDirect XQuery

Dear XML Friends,

September is back-to-school month and so we've published some required learning materials to help get your brain back in shape! Your assignment: to simplify XML, Relational and Legacy Data Integration using powerful XQuery technologies and DataDirect XQuery. A new technical overview of DataDirect XQuery describes how to get started, and why you should care – read on for more information.

Also in this month's issue, yes, you guessed it – more XQuery learning materials! For people who don't like to read, there's a recorded XQuery Webinar that you can watch from the comfort of your own desktop. And for all the managers on this list, we've got an industry analyst report on XQuery from ZapThink that covers accessing large XML files with DataDirect XQuery. All this and much more – it's a back-to-school XQuery bonanza, all here in the September issue of the DataDirect XQuery eXtra, the world's leading XQuery development e-newsletter.

Sincerely,

1. DataDirect XQuery: A Technical Overview

DataDirect XQuery is an implementation of the XML Query Language (XQuery) you can use to query relational databases, XML, and legacy data, or any combination of these data sources. It offers the fastest, most reliable and scalable XQuery support for all major relational databases, runs on any Java platform, supports the XQuery for Java API (XQJ), and is easily embeddable into any Java program. But just how does it work, and how exactly does a developer go about using it?

3. ZapThink Report: Processing Large XML Files with DataDirect XQuery

A new industry analyst report on enabling XQuery for very large messages has been published by Jason Bloomberg, an Analyst with ZapThink, a leading provider of Service Orientation Research, Advisory, and Expertise. In it, the report states that: "As the quantity of XML in the enterprise dramatically increases, enterprise architects, application developers, and data integration specialists must deal simultaneously with the large number of XML formatted messages on the network as well as such messages increasingly large sizes. The XQuery approach to handling and processing XML is now recognized as one of the best approaches to dealing with the manipulation of information in XML format. DataDirect takes the power of XQuery to a new level in version 2.0 of the DataDirect XQuery tool, adding support for non-XML and non-relational data, XML streaming, and very large message support." Readers can download a free copy of the new report today.

5. Ask the DataDirect XQuery Team (and we'll respond)

Got a question about DataDirect XQuery or XQuery technologies in general? Post a message to the DataDirect XQuery team and we'll respond. This month, Derek asks: "My application receives a large XML document over the network. Now I need to pull various pieces of data from that document. How can I configure XQuery to perform streaming queries against that document in memory without having to write the file to disk or to a database?" Read the answers to this question and more at the DataDirect XQuery Forums today.
