However, the enterprise edition does come at a price to its open source roots. Walter said a small part of the code in the new package is not open source.

"About 10 percent of the functionality is not available as open source," said Walter.

Most of the proprietary code is around administration and deployment. The only end-user part of the Professional edition that is proprietary is a feature around deployment of self-service subscriptions for accessing reports, according to Walter.

Pentaho BI Professional Edition Platform will ship later this month and be priced at US$3,000 per CPU, plus an additional annual support fee of $1,000.
