Suppose we want to model an online library system. The library has books and members. Each book has a name, an author, a summary, and a unique ISBN number. A book can have several copies instances with publisher imprint, a due date, and an availability status. Each member has a name, a unique ID and an address. The library has a large collection of books and enrolled members. Further, the library has a name, an address, and an Org ID for tax purposes. A member can borrow books and return the borrowed books. For both actions, the library will first verify the member by checking their borrow score and will also verify the presenceabsence of the book in the library. A library member cannot borrow multiple copies of the same book, but they can borrow multiple copies of different books. Note every time a member returns a book on time their borrow score increases by and each time they are late their score decreases by A negative borrow score will prevent a member from borrowing books.
