Draw the following

Note: Do not draw by hand

Scenario:

Imagine you are developing a simple library checkout system. Users can borrow and return books.The system keeps track of available and borrowed books.

Part $1$: Sequence Diagram $(7$ points$)$

Identify a specific use case for the library checkout system. Examples: borrowing a book,

returning a book, checking book availability.

Create a Sequence Diagram for the chosen use case.

Include the following elements in your diagram:

Actors: User, Library System

Messages exchanged between the actors

Lifelines representing the actors throughout the interaction

Part $2$: State Machine Diagram $(8$ points$)$

Focus on the Library System itself. Model the state transitions of a Book object within the system.

Identify the different states a Book object can be in $($e$.$g$.,$ Available, Borrowed, Overdue$).$

Define the events that trigger transitions between these states $($e$.$g$.,$ Borrowed event, Returned event$).$

Create a State Machine Diagram for the Book object using UML notation
