We are going to design a library system with E/R diagrams. It should satisfy the following requirements. 1. At any time, the borrower can check the variety, quantity and location of the books in the library. All kinds of books can be uniquely identified by the ISBN. 2. The system can check the status of borrowing and returning books at any time, including the name of the borrower, the number of the loan card, the date of borrowing books and the date of returning books. 3. Anyone can borrow many kinds of books, any kind of book can be borrowed by multiple people, and the library card number is unique. 4. When necessary, additional books can be purchased from the corresponding publisher through the publisher's telegram number, telephone number, zip code, and address stored in the database. 5. We have agreed that a publishing house can publish multiple books, and the same book is only published by one publishing house, and the name of the publishing house is unique. (1). Please draw the E/R diagram. (2). From your diagram, please select ONE Relation and write the code to create the table (only one table).
