Oracle is very good if you're the sort of company that wants to make one phone call and buy a turnkey system to do something very boring, but important, that isn't really core to your company. You simply place one call and say "Hi I need a payroll system for my company with a few 100K employees spread around the world", then Oracle takes care of providing everything from hardware and OS right up to support and training, with each component bearing the Oracle brand. Very few companies can offer that.
