Oracle Database is one of the most widely-used database systems in the world. It's a complicated, many-faceted product. Aspiring database administrators often don't know where to begin in learning it. Author Iggy Fernandez remembers that feeling very well. Today and administrator of multi-terabyte databases for some of the world's largest corporations, Iggy got his start as an Oracle DBA by being unexpectedly thrown into the position, literally overnight. He knows what it's like to be floundering in a sea of Oracle technology, not knowing in which direction to swim. This book, that he wrote, teaches readers to swim.
