International groups, DAX companies, authorities, or German global leaders from the higher small and mid-size enterprises – many of these organizations have one thing in common: at least parts of their IT infrastructure are based on Oracle technologies. To get the most out of these sophisticated but also quite complex products, a profound, substantiated, and practice-oriented expert knowledge is necessary that cannot be acquired by only relying on official documentation or course books. This specific know-how can be acquired via the DOAG by both IT and business professionals, working in an Oracle environment.
