Every RDF store is a relational database management system (RDBMS). As 
you know, an RDF compliant RDBMS simply group sets of RDF 3-tuples by 
statement predicate.

We can't continue to concede the notion of a relational database 
management to SQL relational database management systems (sets of 
n-tuples grouped by Table Name).

Maybe we should start referring to SPARQL compliant RDF stores as SPARQL 
Relational Database Management Systems, just like SQL Relational 
Database Management Systems which have now become synonymous with 
Relational Database Management System. Then "just a little more" becomes 
much closer to demonstrable reconciliation of "the truth, the whole 
truth, and nothing but the truth, in regards to relations, databases, 
and database management systems" :)

ACID has nothing to do with what constitutes an RDBMS either, that's an 
a useful, but optional feature of any RDBMS. So don't fall for that 
baloney laden push-back when taking the SPARQL RDBMS position.

We MUST end the SQL RDBMS power-grab! It has done a major disservice to 
the entire DBMS industry, over the last 40+ years. You have a 
multi-billion dollar industry that's fundamentally about companies and 
individuals that are data-access-heavy and data-exploitation-challenged 
i.e., they have tons of data ("Big Data" these days), but still can't 
achieve basic agility goals in regards to: accessing, integrating, and 
moving data effectively to the right people, at the right time, in the 
right form, and in appropriate context etc..
