The book contains references for every data source it uses, all of them are available as Open Data. So you can load all the data, and copy/paste all the SQL queries with just the Book Edition.

The Full Edition isn't so much about the code contained in the book (SQL queries) as it is about having the very database used in the book handy to replay the queries.

I understand that the Full Edition doesn't make the same value for everyone, and it's fine. That's why it's not the only option. Given how many are sold compared to the other options, I'm confident it still is a solid option though.
