b) State diagram is one of the diagrams of UML. With the help of a suitable example of state
diagram, explain the terms: state, transition and event.
c) A Book-Bank Membership Software (BMS) should support the following three options: new
member, renewal and cancel membership. When the new member option is selected, the
software should ask for the member’s name, address and phone number. If proper information
is entered, the software should create a membership record for the new member and print a bill
for the annual membership charge and the security deposit payable. If the renewal option is
chosen, the BMS should ask for the member’s name and the membership number. If the
member details entered are valid, then the membership charge payable by the member should
be printed. If the membership details entered are invalid, an error message should be displayed.
If the cancel membership option is selected and the name of a valid member is entered, then
the membership is cancelled, a cheque for the balance amount due to the member is printed
and his membership record is deleted. Draw the decision tree for BMS.
