Lesson 2 - Create a related entity

In this lesson, you will define the book_review entity, which will allow you to record and connect book reviews to the book entity.

In the next section, you will add an operation to create new book reviews. This operation will use the ISBN to link each review to a specific book.

Finally, you will learn how to write a query to retrieve all reviews associated with a particular book, using the ISBN as a reference.
