I'm a software developer in Sydney, Australia, and I've just finished v1.0 of the object-relational mapper I always wanted to write. More importantly, it's the tool I'll always want to use, any time I'm writing a C++ application that talks to a relational database.
It's called "quince", it's open-source, it's free of charge, and you can read all about it at http://quince-lib.com .
