Most of the time nobody will need SQL. And having a transparent,
transaction-aware and undoable persistent Object store is really a cool
thing. But from time to time you will hit walls. That's when the object
paradigm just does not do the job completely well any more. E.g. how would
you handle objects beloning to more than one container? In SQL this is easy
(Just have a table that matches key pairs from the container table and the
item table). And I don't know any good way of implementing "many-to-many"
relations in object hierarchies. Let alone querying them efficiently.
