- Create an ERD for the given scenarios. Thank youu!! Each publisher has a unique name; a mailing address and telephone number are also kept on each publisher. A publisher publishes one or more books; a book is published by exactly one publisher. A book is identified by its ISBN, and other attributes are title, price, and number of pages. Each book is written by one or more authors; an author writes one or more books, potentially for different publishers. Each author is uniquely described by an author ID, and we know each author’s name and address. Each author is paid a certain royalty rate on each book he or she authors, which potentially varies for each book and for each author. An author receives a separate royalty check for each book he or she writes. Each check is identified by its check number, and we also keep track of the date and amount of each check. As you develop the ERD for this problem, follow good data naming guidelines.In Chapter 3 of Sharma et al. (2010), you will be introduced with a case study: "This case study describes a simple Library Management System. Assume the requirements for the system were written by your client exactly in these terms: The system will manage the author's and loaner's information, and keep track of books loaned. The borrower's information includes name, address, e-mail, and phone. The author's information includes name, address, and e-mail. New books, authors and clients are entered into the system. When a client checks out a book, the system will register the date the book was loaned and calculate the days the book can be loaned. It will also calculate the date the book is due to be returned. If the borrower returns the book late, he must pay a fine based on the number of days overdue." (Sharma, et al., 77).
