However, Reeves said, Oracle executives have given mixed messages about the future of the Siebel middleware products that EDS uses. Depending on Oracle's plans, EDS may have to replace the Siebel middleware with software from Oracle. "It's an open question for the future," she said.

At a press conference during the show, John Wookey, vice president of application development at Oracle, said the vendor plans to continue supporting both the Universal Customer Master and Universal Application Network middleware.

He also said the company plans to use Siebel middleware technologies in the Fusion middleware it is building.

Reeves also said she hopes that Oracle takes steps to ease the process of migrating to new versions of Oracle tools. The process is now costly, she said, mostly because of EDS' need to customize each new version.

"Easing that migration and helping customers upgrade without significant financial drain is very important," she said.
