where is the "books" demo database scripts for PL/SQL Programming?

Edit Subject

I have searched both oreilly.com/catalog/oraclep4
and oracleplsqlprogramming.com

and neither points to the demo data used in the 1000 page book?

How can a student learn the materials in the book, without the database installed?

This is my greatest complaint with so many programming books.

They point to the sample code... but one can't do anything with sample code, WITHOUT the DATA!
