Pentaho Announces Mondrian 2.4

New Release Provides Enhanced Analytics and Improved Support for Large Databases

ORLANDO, FL--(Marketwire - September 5, 2007) - Pentaho Corp., creator of the world's most popular open source business intelligence (BI) suite, today announced Mondrian 2.4, the latest release of Pentaho's popular Mondrian OLAP project. The new release provides additional analytical capabilities along with advanced SQL enhancements to optimize query performance against very large databases.

Mondrian 2.4 provides the ability to intelligently aggregate distinct-count measures. As an example of the business application of this capability, consider someone trying to analyze the number of customers their company had sold to over a six-month time period. Adding the number of customers for the individual months would lead to an inaccurate result, because a given customer could easily appear in several different months. Mondrian 2.4's new capabilities make it easy to identify and analyze distinct-count measures such as these.

Mondrian has been deployed for production applications analyzing more than half a terabyte of data in a multi-server, clustered environment. As data volumes grow, it's critical for OLAP applications to exploit the performance and scalability features of the underlying database platform. Mondrian 2.4 now supports the GROUPING SETS SQL construct, to improve performance and reduce the number of individual SQL queries required to satisfy an analytical request. This SQL construct is widely supported in popular commercial database platforms, including IBM DB2, Microsoft SQL Server, Oracle, and Teradata.

Mondrian 2.4 also supports additional Multi-Dimensional Expression (MDX) functions, improved support for the industry-standard XML for Analysis (XMLA) web-services protocol, and integration with the Apache Virtual File System (VFS).

Since its inception in 2000, Pentaho's Mondrian OLAP Project has become the world's most popular open source OLAP project, with a large and vibrant open source community as well as an extensive list of large-scale production OLAP applications around the world. Mondrian addresses end-user organizational needs across multiple different industries, and has also become a popular choice for ISV's and OEM's looking for embedded OLAP and professional support from Pentaho.

"We continue to expand Mondrian's analytical capabilities, and to drive greater performance and scalability," said Julian Hyde, founder of the Mondrian project, and chief OLAP architect at Pentaho. "Mondrian 2.4 addresses a number of user requests, and is a great achievement for our team and our community."

Subscription services, consulting, training and IP indemnification for Mondrian are available now from Pentaho. For more information, please see Mondrian 2.4 is available now for download at
