Iggy Fernandez has a rich history of working with Oracle Database in many capacities. He is the author of Beginning Oracle Database 11g Administration (Apress, 2009) and teaches Oracle database administration at University of Washington Professional & Continuing Education. He was the president of the Northern California Oracle Users Group (NoCOUG), the longest running and most active Oracle users group in the world. He writes regularly for the NoCOUG Journal and has been its editor for many years. Iggy's favorite topics are database performance and SQL performance, and he regularly speaks on these topics at Oracle conferences. He has a lot of opinions but is willing to change them when confronted with fresh facts. His favorite quote is ""A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines - Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing yousaid to-day."" - Ralph Waldo Emerson.
