To build on this question a little, many times in a RDBMS setup you Car and
Truck would end up being three tables, with a Vehicle polymorphic table as
the base. I get how to distinguish cars vs. trucks, but what about when I
want to treat them the same, to treat them like Vehicles? I want to see all
Vehicles, without having to list each one out? I've seen how couch can do
joins, but it's still not apparent to me how to do inheritance.
