I was the interface between Oracle Sales and management at a start up a long time ago. It was weird. They offer technical help to use their API, (so its harder to switch away, I was told by my boss). We were on using on a trial basis. They seemed to want to charge based on CPU speed of the computer installed on. The startup ran out of money...
