Oracle Presidents Safra Catz and Charles Phillips shared the stage Monday morning at Oracle OpenWorld to reaffirm Oracle's commitment to integrated applications and product suites.

Oracle's frequent acquisitions will ultimately serve that purpose, Phillips told the crowd. Instead of shipping customers the parts of a car that they must assemble in their garage, Oracle wants to ship the whole vehicle.

"That's what all those acquisitions have been about -- so we can send you a complete car," he said in his keynote address at the San Francisco Moscone Center. "We have 20,000 developers working year round to integrate" the acquired products, Phillips added.

"We can't send a complete car unless we have all the pieces," said Catz.

The two presidents also pledged a full integration of Sun Microsystems "hardware and software," once Oracle's acquisition is completed, pending the outcome of a European Commission investigation. "We will do the same thing with Sun hardware and software that we've done with all the other acquisitions--make them better," said Phillips.

Oracle CEO Larry Ellison and Sun Microsystems Chairman Scott McNealy appeared together Sunday on a stage at the Moscone Center to vow that Sun's hardware and other technologies will be continued after the two companies are merged.

Oracle announced its plans to acquire Sun in April and the U.S. Justice Department approved the deal Aug. 20. But on Sept. 3, the European Commission launched a secondary investigation in the possible anti-competitive aspects of the deal.

Late last year, Oracle acquired project management software supplier Primavera. Phillips invited Joel Koppelman, Primavera's founder and now senior VP of Oracle's Primavera unit, on stage to illustrate the integration of Oracle P6 Primavera Project Portfolio Management with Oracle E-Business Suite, J.D. Edwards, PeopleSoft, Agile and Spatial applications, all acquisitions by Oracle.

The integrations are needed because projects are frequently revised while underway --"there are always changes," Koppelman said -- and project managers need to enter those changes into accounting and budgeting applications. Without links to financial applications, project management can only show funds committed to a project and the amount already spent, without reconciling the figures if more needs to be added to the budget, Koppelman noted.
