Show Host Scott Hayes Commentary

When I first met Ember several years ago at an IDUG conference, she was so shy she was practically hiding under her chair so that no one would talk to her. Now she's an excellent blogger at, a published author on IBM Developer Works, a multi-year speaker at IDUG, an IBM Information Management Champion and DB2 GOLD Consultant, a DB2's GOT TALENT 2013 3rd place winner, a regular guest on The DB2Night Show™, and, in general, a leading advocate for the DB2 community! What a change! I'm proud of you! On behalf of the DB2 Community, thank you very much for bringing your DB2 real-life lessons learned to public forums so that we can all benefit from your trail-blazing experiences!
