What means NoSQL?
As far as I remember NoSQL meant originally just that no SQL is required in order to work with the underlying database system. I am sure that the most of you are knowing the S(tructured)Q(uery)L(anguage) from the relational database world. The theory behind it is based on the relational algebra. Since new (or even renewed) concepts are used for non-relational databases, also other ways to access data are used. In the meantime conceptional parts of the relational algebra were taken over to non-relational databases, too. So the 'No' stands now for 'Not only'.
