I'm trying to get my head around why SQL composite types are a good
way to marshal complex object graphs with recursion.  I can see
where it could be done, I'm still not convinced that it's better
than SQL passing out data in tabular form with relationship
established by matching values.  In other words, when is it a good
idea to do the relation to object mapping in the database engine?
