For anyone attending Oracle Openworld in San Francisco we have put together a paper on all the Oracle Application Express sessions, hands-on-labs, demo ground details, etc.
From the link above, select 'Customized Schedules' in the Sessions, Keynotes and Exhibits section and then scroll down to the Technology "Focus On" papers.
I suggest you download the FOCUS ON Database Application Development – Oracle Application Express paper to ensure you don't miss any of the great APEX sessions and labs.
Another useful "Focus On" paper is FOCUS ON Database Application Development – Oracle SQL Developer.
Look forward to catching up with lots of people throughout the event.
