Here's why you post doesn't help, it makes no mention of Relations.

A Relation is a set of Relationships.

A SQL RDBMS represents Relationships using Records. The Relations is 
denoted by a Table Name, it is comprised of a set of Relationships.

A so-called Graph DBMS (which has been called many things over the years 
from CODASYL/Network --> Deductive --> Object Oriented --> 
Object-Relational --> Graph / Property Graph etc..) represents 
Relationships using Statements or Claims (either way: Propositions). The 
Relation is denoted by the Predicate/Property of the Statement that 
represents the claim or proposition. Basically, the Relation is a set of 
statement/claims/propositions.

RDF has taken on the admirable task of decoupling Data from the tyranny 
of RDBMS products. In the process though, many of its evangelists and 
narrators got a little too giddy and opted to pile everything into the 
RDF bucket. Net effect, eternal confusion.

Your post is full of generic terminology presented is a confusing 
matrix. It looks nice, but its doesn't actually address the reality of Data.

BTW -- "Data" is a literal denotation of the concept of using entity 
relationships to express observation. I you agree to that definition, 
you are on you way to really groking and appreciating RDF and the real 
problems its addresses when combined with HTTP URIs (or other URIs for 
which resolvers exist).
