The text above figure 3.1 states "Figure 3.1 shows a partial database diagram the Books and Review tables." The image actually shows the relationship between Books and Authors with the BookAuthor link table. The text should probably also say "... shows a partial database diagram OF the Books and Reviews tables."

Yes, you are right! The text is correct, but the diagram is wrong. The original was "Creating a book with an Author", but that made the example too complex this early in the book, so I changed it to "Creating a book with a Review", but forgot to replace the diagram.

Thanks for reporting that. I have load of other fixes and I have added this to those.
