-relational, distributed, does not provide an acid database design pattern.The No:sql (East) symposium, held in Atlanta in 2009, was a milestone with the slogan "Select Fun, Profit from Real_world where Relational=false;". Thus, the most common explanation for NoSQL is "non-relational", emphasizing the advantages of Key-value stores and documentation databases, rather than simply opposing RDBMS.Based on 2014 years of revenue, the
