Until the recent 2009, Ellison was also the largest cloud-computing attacker in the IT industry. He questioned what the cloud was, accusing VCs of being fashionable and refusing to accept cloud computing as the current buzzword. Since then, however, Ellison's view of cloud computing seems to have changed. Now, Ellison stands out to tell the benefits of Oracle's growing cloud of products.

Despite being caught by Oracle, the controversy on MySQL never stopped; today, MySQL is still the most popular open source database on the market. Simple, free, extensible, relatively mature and so has always been the attraction of MySQL, but it is like a rabbit in a tortoise and hare race, because of its own advantages, to slacken, slowing down their own pace, so that each competitor Have the opportunity to catch up, these killer features are no longer attractive (or even reduced to the disadvantaged). Although PostgreSQL has always been the direct competitor of MySQL, ...
