Tuesday March 30, the Dutch Oracle usergroup OGh organizes one entire day dedicated to APEX. I'm a little biased, as I helped organizing the event, but I think we succeeded in putting together a great program, as you can see here (warning: Dutch). The lineup includes some very well known APEX speakers like Patrick Wolf, Dimitri Gielis and Roel Hartman.
The schedule also includes three sessions where you'll hear from companies who have chosen APEX as their development tool of choice. So if you need to convince your boss to choose the tool that matches the skill set of his team members, send him or her to this day. And be quick, because there are only 7 places left, as of this moment.
Hope to see you there.
