The interface is similar to Windows Explorer.
The program is based on the Windows Explorer user interface: The program contents are displayed in a tree structure in the left window, while the master data for the selected student (preset here: Monika Mustermann) is shown in the right window. The width of the two windows can be adjusted by clicking and dragging the window divider bar with the left mouse button held down. Clicking on a plus sign opens the next level of detail, while clicking on a minus sign in the tree closes a level of detail.
