What's New in DataDirect XQuery 3.1

The DataDirect XQuery® product is an XQuery processor that enables developers to access and query XML, relational data, SOAP messages, EDI, legacy, or a combination of data sources, and, in addition, provides full update support for relational data.  DataDirect XQuery supports the XQuery for Java™ (XQJ) API, and is easily embeddable into any Java program — it does not require any other product or application server, and has no server of its own.  It is recommended for developers who need to combine and efficiently process XML, relational, and legacy data formats in application scenarios such as data integration, XML-based data exchange, XML-driven web sites, and XML publishing. DataDirect XQuery vastly simplifies and enhances the performance of combining and processing different types of data (relational, XML, legacy, EDI, and more) in heterogeneous environments and thus enables developers to build and deploy high-performance applications quickly and efficiently. 

Highlights of the DataDirect XQuery 3.1 release include:

• Expanded database support including XQuery support added for MySQL (Enterprise version) and additional databases such as Oracle 11, Informix, and PostgreSQL.
• Increased developer productivity with the direct support of ZIP files containing XML documents and the ability to transparently generate EDI as output of an XQuery using the DataDirect XML Converters.
• Enhanced Web service integration simplifies using XQuery in SOAs.

Release Highlights

Here's a summary of what's new in Release 3.1

• MySQL support – Users with MySQL database deployments (Enterprise version) can now take advantage of all the benefits of DataDirect’s XQuery engine. 
• Extended file type support and output enhancements – DataDirect XQuery increases productivity for developers who need to work with ZIP files composed of XML documents or requiring EDI output formats by eliminating intermediate processing steps.  DataDirect XQuery can query, in a streaming fashion, XML files (ie, OpenDocument, Office Open XML, PDFs) which are packed into ZIP files directly without the need to unzip them first.  The output of an XQuery can now be EDI directly, eliminating the separate conversion step for the developer. 
• Enhanced Web Services integration – DataDirect XQuery provides support for SOAP (including automatic integration of output XML Schema in the generated WSDL) and REST as well as added support for configurations and connection pooling. 
• Additional database support – Support added for DB2 v9 on z/OS, Oracle 11, Informix 9.4 & 10, and PostgreSQL 8.1 & 8.2.  Check the complete list of supported databases for your specific database or version.  If you need to support a database or version that is not listed, email us at xmlinfo@datadirect.com.
