"You have a choice, and I'm pro-choice. The guys at Salesforce.com are not pro-choice," he said.

Ellison defended the delays in Fusion's release.

"It took a little longer than we planned but it was a huge, huge engineering project to present a huge integrated suite ... with all the different pieces rebuilt on top of modern technology. It's complete, integrated and finally here," he said.

Ellison described how Oracle along with customers "worked and reworked" the software until it was complete.

Security is built into the underlying infrastructure, Ellison said. "We didn't put security into Fusion Applications, we upgraded the infrastructure so it's built into the virtual machine and the operating system and the database. Anything built on top of that infrastructure is secure. That's especially important in the world of the cloud and the public Internet."
