A 4-day training session in ASKOM facilities enables the basic skills required for designing and starting-up the application to be learnt. Each participant will be assigned to his own computer with the latest asix version installed for training purposes and will be taught how to construct an application from scratch. We also share our knowledge about various untypical solutions facilitating and shortening the design works; we reveal many hints improving the software maintenance and application development. Some of the information presented during the training session cannot be found in any manual. The participants check their new knowledge and abilities during the creation of their own original application built during the course.
