My personal favorite is "Principles of Transaction Processing" by
Bernstein and Newcomer, ISBN 1-55860-415-4
This book is pure gold!

>I recommend that anyone seriously interested in transaction processing
>read "Transaction Processing: Concepts and Techniques" by Gray and
>Reuter, at least chapters 1 through 7, and chapter 10 "Transaction
>Manager Concepts".
>
>Chapter 7 "Isolation concepts" presents the main isolation theorems in
>an easy mathematical form. When you read the theorems and their proofs,
>you will notice that there is NO MENTION OF RELATIONAL DATABASE
>STRUCTURES. Thus we're talking about OBJECT TRANSACTION PROCESSING.

>As to consistency in ACID, here's a passage from page 166 in chapter 4
>"Transaction models":
>
>>>Consistency:
>>>A transaction produces consistent results only; otherwise it aborts. A
result is consistent
>>>if the new state of the database fulfills all the consistence constraints
of the application;
>>>that is, if the program has functioned according to specification.
Simpley as that may seem,
>>>it has a number of subtle ramifications ...
>>>Here, then, is the other way to put it: data is consistent if it has been
produced
>>>by a committed transaction. This is where (in today's systems at least)
the definition
>>>becomes somewhat circular. ...
>>>It is important to keep in mind that the consistency definition that
comes with the
>>>transaction paradigm is largely a syntactic one.
