There are large conferences, and then there is Oracle OpenWorld. A mega-conference that sees over 40,000 attendees descend on San Francisco.
The topics covered are as diverse as Oracle's software stable: everything from databases, middleware, enterprise resource planning and business intelligence software.
A number of celebrities are also attracted to the conference; this year California Governor Arnold Schwarzenegger, Roger Daltry and many company CEOs shared the stage with Larry Ellison.
Chris Duckett travelled to OpenWorld as a guest of Oracle.
