Good books on the theories behind UML/data modeling for web apps?

Trying to better my grasp on this area of app开发者_StackOverflowlication design/architecture/development and looking for any suggestions in this area. I have read some other posts and have a list of development theory books, but would like to form a list for more architecture based books that relate to web based applications. Thank you!

First thing that jumps to mind for me is Patterns of Enterprise Application Architecture by Martin Fowler.

http://books.google.ca/books?id=FyWZt5DdvFkC&dq=patterns+of+enterprise+application+architecture&printsec=frontcover&source=bn&hl=en&ei=jr9XS6H-J4KY8Abs_eXJAw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBgQ6AEwAw#v=onepage&q=&f=false

Addendum

Damn! Poking around on Martin Fowler's Web Site I found "Refactoring HTML: Improving the Design of Existing Web Applications" in his signature series...

It looks quite interesting. Its material focuses on moving away from "tag soup, presentation-based markup and stateful applications" towards "XHTML, CSS and REST."

Haven't read it but it sure looks promising.

I have the good old "Building Web Applications UML" in my bookshelf, but yeah it is only worth the 5 bucks for which you can order it from amazon.

http://www.amazon.com/Building-Web-Applications-UML-2nd/dp/0201730383/ref=sr_1_1?ie=UTF8&s=books&qid=1264090325&sr=8-1

Not that the book is bad but IMHO UML for web apps doesn't make really sense.
