Larry Ellison was having too much fun. In his second keynote of this year's Oracle OpenWorld user conference, he was talking about his company's database, Oracle 12c, and comparing it highly favorably to Amazon's competing databases. It seems Ellison always has fun, which is one likely reason that the 72 year-old CTO and executive chairman of the board, looks 52, sounds 42, and probably feels 32. Ellison's sunny attitude no doubt was enhanced by Oracle's last earnings call, which delivered very good news about a company that has been working on pivoting to cloud computing for several, even many, years.
