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)
