True and it's unclear how usable cheaper options will be without those files. It's pretty much a de facto standard that source code going along a technical book is available for free. This is too bad because I would have purchased it instantly otherwise.

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.

Yep, the only version that's attractive enough (enterprise) is about 3/4 of the minimum wage here. I can't buy it, and it's a hard sell to my bosses, especially when the company doesn't even have more than 10 employees.
