Think about your school or local library and the processes involved in checking out books, signing up new borrowers, and sending out overdue notices, all from the library's perspective. Describe three use cases that represent these three functions.
• Create the use case diagram for the library system.
• Choose one use case diagram and create a sequence diagram.
• Create a class diagram for the library system.
• Create a behavioral state machine diagram to depict one of the classes on the previous class diagram.
