Techopedia explains Oracle OpenWorld
At OpenWorld events, senior Oracle managers and product specialists hold various talks or seminars to explain various features and functionality of Oracle products. The product briefings typically consist of Oracle subject matter experts giving talks, hands-on lab sessions, product demos and exhibitions. The event is important in Oracle's annual calendar, so senior-level managers like CEO Larry Ellison and president Mark Hurd also usually give keynote speeches.
Oracle produces applications almost exclusively for use in business environments, unlike that other software behemoth Microsoft, which sells software products for both individual/ home users as well as organizations. So OpenWorld attendees are mostly corporate IT decision-makers.
