Thank you very much Robert.
Very simple and clear example of dealing with one-to-many relationships.
This must be an elephant tutorial.
Although cascading deletes are indeed a nice feature of sql servers, I'm
fedup with sql inflexibility dealing with complex hierarchies of objects. I
want to try OODB. Elephant is the only choice in a lisp land. Allegrocache
is expensive, rucksack in its infancy.
So far I like it.
