"Just because the application is in the cloud doesn't mean you don't have to do any work," he said. "You're still going to have to interconnect these applications. Therefore we provide a platform to do it."

While Fusion Applications' SOA (service-oriented architecture) makes it easier for customers to make these connections, there's more to it than flipping a switch, he said. "Otherwise Deloitte wouldn't have a big cloud practice. Accenture wouldn't have a big cloud practice. They must be doing something."

Ellison repeated statements he made earlier in the week regarding a new multitenancy feature in Oracle's upcoming 12c database. The feature will allow a number of "pluggable" databases to reside in a container.

This approach is superior to the form of multitenancy used by most SaaS vendors, according to Ellison.

"We think you should not commingle two customers' data in the same database," he said. "You can still share hardware, have shared resources and operate efficiently. We just don't think you should write an application with multitenancy at the application layer."
