This program is a study project. The requirement was to prepare the app in Polish. A purpose of the app is connecting to a database (set up locally) to show or insert data. The database consists of driver and bus data, bus stops, bus line (route), ride and their relationships.
The app has really simple signing in. Any user can see simple info about any bus and check a timetable or routes between 2 stops. User logged in as a driver can obtain all information from any table. If you sign in to admin account you can additionally insert a new record to any table. The database checks if data are valid (driver/bus can have only one ride at the same time or there cannot be a bus stop twice) and raises exception (showing an error dialogue window) otherwise.
