Ellen Novotny started an online bookstore in 2017. You are Ellen's best friend and promised to help her. Ellen asked you to create a small database to track the information on books and authors. You created the following tables: Author. Book, and Author Book. The table Author_Book is a relationship table to link the Author table and Book table because of the many-to- many relationship between the two tables. That is, each author may write many books and each book may have multiple authors. In general, each customer can purchase many books in a single transaction. Also, copies of the same book can be sold to different customers. Once an order is processed, the books are shipped right away. Based on these tables you have (see below), help Ellen to extract the information she needs from the database.
