Watch Iron Man 3 closely enough and you'll find two references to Oracle (NYSE:ORCL), the database giant that's had trouble diversifying into hardware. Will associating with a billionaire computer genius -- even a fictional one -- aid sales? CEO Larry Ellison seems to think so.

The first time Oracle appears in the film, Tony Stark asks computer assistant J.A.R.V.I.S to help him narrow a national search for clues to a crime, after which the Paul Bettany-voiced system responds that it had "engaged the Oracle cloud." The second time, a "Sun-Oracle" sign appears above Stark as he prepares to reconfigure the Internet signal of a satellite truck.

We've seen this before: Ellison appears as himself early in Iron Man 2. And why not? Ellison, like Stark, is a brash billionaire heading a tech empire. The difference is that Oracle is taking risky bets to overcome stiff competition from salesforce.com (NYSE:CRM) in the cloud and Cisco (NASDAQ:CSCO) in networking gear. Enjoy the hype, but don't be too quick to buy Oracle stock, says Fool contributor Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova.
