1. Draw an ERD for the following situation. Be sure to show: entity information, attributes, identifier(s), relationships and relationship names, and cardinality. Each publisher has a unique name; a mailing address and telephone number are also kept on each publisher. A publisher may publish 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 may write 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. As you develop the ERD for this problem, follow good data naming guidelines
