thank you.

Consider a software system for supporting check out of materials at a public library:

1.List three actors. Explain the relevance of each actor.

2.One use case is to borrow a library item. List three additional use cases at a comparable level of abstraction. Summarize the purpose of each use case with a sentence.

3.Prepare a use case diagram for a library check out system.

4.Prepare a normal scenario for one use case.

5.Prepare an exception scenario for one use case.
