Since there is not a diagram for a hospital, it may have been better not to include that explanation. The definitions aren't very clear. For instance, the author mentions business rules, which is great. But, doesn't truly tie an example to the diagram. Lack of discussion on cardinalities is a problem. I wouldn't use it as a teaching tool, unless it was to give students the opportunity to complete it.
