True, but some set of propositions can't be stored in as systematic a
manner (ie without NULLs and redundancy) as with a node-based database
like dbd. Try to represent the following 3 propositions involving
three persons:



john hates john


mary knows (john hates john)


sue knows (john hates john)



For a bonus, include the following:


bob knows (john hates)
