[Rails] Mapping Objects to Relational Databases

[Stefan Arentz]

For those interested in strategies for mapping object inheritance to a 
relational database, there is a really good article by Scott W. Ambler 
called "Mapping Objects to Relational Databases".

It used to be at http://www.ambysoft.com/mappingObjects.html but it 
looks like the author has replaced it with a collection of related 
articles that cover the same stuff. Still a good read though.
