As Stéphane pointed out a few months ago, the Training department launched a new course named PI Application Development (see this discussion thread).
We are pleased to make the class materials (presentation + exercises) available on vCampus, should you wish to go through the course yourself. It is available under the vCampus Training Center - or you can download it directly from here. If you would like to provide feedback to the Training department, you can use the "Training & Online Courses" discussion forum. And do not hesitate to post technical questions on the other discussion forums.
