is necessarily, different. I believe that it probably is hard for a
person equipped only with the high school math apparatus. To give
credit where it's due, I have to say that the part about .trc file details and the perl scripts dealing with it are worth buying the book.

I have however read Cary's book from cover to cover (including spending rather too long on a romantic weekend in paris with my wife contemplating a 10046 trace parsing project :(). I Am rereading and intend to require my fellow DBAs and sysadmins to read it. However to attempt to answer your questions.
Yes it is different from every other tuning book out there (though
there
is *some* overlap with Christpher Lawson's 'the art and science of
oracle performance tuning'). The difference is exactly in the approach
-
the central thesis of the book is (something like) that by utilizing
well specified and targeted extended sqltrace data for problem user
actions the Oracle performance analyst can quickly and efficiently
resolve Oracle performance problems that debilitate the business
performance of Oracle based systems. This approach - to target problem
business processes, find out why they run slowly and optimize them, is
exactly what the RDBMS world needs (IMO).
In addition the method Cary and Jeff describe predicts when it will (and more importantly) won't be of use.
Is it more readable than others? Here I do have some reservations. The
first and last third of the book are extremely readable, and the
character and humour of the authors shines through. The formal
central
section will put off some (maybe a significant number) of readers
though. Stephen Hawking in 'A Brief History of Time' writes "Someone
told me that each equation I put in the book would halve the sales. I
therefore resolved not to have any equations at all. In the end,
however, I did put in one equation, Einstein's famous equation E=mc�."
Cary and Jeff have either not been given this advice, or ignored it in
the interests of accuracy. The advantage that this gives is that the
book has a formal methodology that puts others to shame - the
disadvantage is that folk look at pages filled with equations full of
queueing theory and Greek symbols and react badly. I hope that the
advice is wrong, but fear that it may not be.
