In February, Oracle picked up some intellectual property assets from privately held Ndevr, maker of software for environmental reporting and analytics, followed by last month's purchase of data quality vendor Datanomic. Sale prices were not disclosed in either instance, suggesting they weren't material to Oracle's bottom line.

Oracle's biggest acquisition in recent years was Sun Microsystems, a US$7.4 billion deal that closed in early 2010. Since then, Oracle has been working to shore up Sun's hardware business and started pushing a vision of integrated systems spanning from disks to applications.

While those efforts as well as the long-awaited Fusion Applications launch are likely keeping Oracle officials busy, it seems doubtful the company is through buying vendors.

For one, Oracle CFO Safra Catz to former Hewlett-Packard CEO Mark Hurd's experience "operating a $100 billion business" as a reason for as co-president last year, and it seems unlikely that Oracle intends to get to such scale solely through organic growth.

However, Oracle may also be no longer interested in gaining scale by consolidating ERP (enterprise resource planning) vendors, as it did with high-profile purchases like PeopleSoft, which had previously bought JD Edwards. Some for vendor Lawson Software in recent months, but original suitor Infor appears to be walking away with the ERP company in a $2 billion transaction.
