Content on this blog reflects my personal viewpoints and not necessarily or likely those of my employer. Professionally, I obsess rather compulsively about the Oracle PL/SQL language, having written ten books on the topic, all published by O'Reilly Media. I am the PL/SQL Evangelist at Quest Software, Inc. I've been developing software since 1980. My current focus is on enabling active education on the Oracle technology stack through online quizzes, which you can check out at the PL/SQL Challenge: plsqlchallenge.com.
