In Chapter 8, we described a database with two entities, COURSE and INSTRUCTOR. “Book” was left as an attribute of COURSE. Extend the database to include book as an entity. Attributes of book might include book title, author, price, edition, and publisher. Explore the relationships that might exist here: use “in” or “by,” “write,” “teach,” and so on. Draw an ER diagram with at least two relationships, one of them ternary. What would be some attributes of the relationships?
