"In the field of educating students or IT-professionals, this tool gives you much support and wonderful help to increase their knowledge. Beside of theoretical background, it gives the possibility to consolidate the knowledge by practical experiences. Only this mixture of theory and practice leads to real understanding."
Prof. Dr. sc. nat. Christoph Meinel, Uni Trier
