The models can be used free of charge - the book goes through the decisions
in to why you create the models as devised in the book and how to make
possible modifications if necessary. The CD-ROM for book is licensed
seperately and only contains the SQL scripts and diagrams for casing tools
for the models. They are not required in any way to implement the model. It
is definitely well worth the money ~$55.
