In search for an ORM

Sharan has been searching for an ORM for C++. Though we have been able to find many for Java, python etc; couldn't find one which is popular for C++.

A few that I found, though we yet to evaluate are:
http://soci.sourceforge.net/
http://sourceforge.net/projects/open-orm/
Database Template Library: http://dtemplatelib.sourceforge.net/

Found this one mentioned at a couple of places; but the page just refuses to open up
http://ceamus.com/objbuilder/

If anyone has any better suggestions, let me/sharan know.
