How the User Interface behaves
The interface allows the users to input login username and password which must be
authenticated before the access is granted. In case of wrong input of username or
password, the application produces an error message prompting the user to input correct
username or / and password. Also if the user input the correct username and password,
the program informs the user that he has successfully logged in. The following User Case
Diagram (see Figure 10) displays the functionality of the system.

Figure 10:
User Case Diagram
As shown in Figure 10, the student can view personal details, chooses the residence and
room, and finally sends the application form. He/she can view and print reference
number, retrieve, edit or cancel his application form. The administrator processes
payments for each student who applies while the Residence Manager allocates room to
student and both can retrieve, edit or cancel information.
