The problem is that the relational database of tables has no relationship to how humans store information, we humans use graph structures to relate information. This is why RDBMS are a dead end in getting closer to understanding.
Besides, I'd say that it's not quite clear how we store information. I myself would point to sets as to a worthy contender.
Commenter is self-promoting their "graph DB" related product.
