Fortune 500 Rank: No. 80
Revenue: $37.1 billion
Top Executive: CEO Larry Ellison
Redwood Shores, Calif.-based Oracle inched up in its rankings from No. 82 last year. Though one of the industry's leading software vendors, the company has struggled a bit recently as it works to convince customers to buy its complete "Engineered Systems" that combine hardware and software in complete turnkey packages.
Still, the company remains the database software market leader and is a major player in most every other software category, from middleware to applications.
