Is there any NoSQL DB implementation that has none separate daemon?

I do look for a simple NoSQL DB that such as Sqlite DB, i.e. that does not need to install a separate daemon. All files needed should be in my PHP开发者_开发技巧 application tree. Do all NoSQL DB implementations need a separate daemon to be usable?

Berkeley DB

The webpage above is very marketing oriented. Take a look also at the Wikipedia page

GT.M is another solution you should have a look at.

ZODB? it is OO DB and follows NoSQL (Not Only SQL)
