In GSG 7.0 and 7.5 inclusive, Chapter 8, Base the section “planning a database” uses a theme of a db for automotive costs, repairs, and so on. Then the theme changes to a CD music database, and following that the theme changes back to the automotive database. The reading would flow better if the same theme was used rather than jumping around. That would help the continuity of thought in starting a database for the first time.
