All of the generated data is plausible, but not the real data. If you want the ebook, it can be ordered from the same link below.

If the UR isolation level was specified for the second transaction, it would read the changed data even though it had yet to be committed. Your webmaster has put past editions of this book to good use and considers the money well spent.
