 # Example Scenario
-Assume that your customer wants you to develop a web application called "StudentData" which is similar to the StudiDB. This application must be accessible by students, lecturers, and administrators. All of these users must be able to register and to login. For this purpose, an external authentication service is used. Students can join lectures and view their exams taken so far. Furthermore, they are able to drink multiple coffee drinks simultaneously. Lecturers can assign grades to students and print reports with statistics about their lectures. Administrators can add users and lectures.
