The links for Martin Fowler's and Scott Ambler's sites are good links for an overview of O/R mapping. To see real code (since I can't make mine available), check out http://objectbridge.sourceforge.net. Way back, it was this project that got me started on my O/R project by a simple port to .NET. Since then, my own O/R mapper has taken a different tack, but it's a good example to examine.
