Is the same as "C++" and "OOP". An "SQL database" is an implementation of a "partial" and inconsistent version of the relational model. So is not wrong, IMHO,

Is the same as "C++" and "OOP". An "SQL database" is an implementation of a "partial" and inconsistent version of the relational model. So is not wrong, IMHO, to say "SQL databases" to be "Relational Databases" (nitpicking as "Relational-inspired"). Is not that the relational model as first envisioned is perfect. Is ok to implement "partially" and also "extend" the vision it provides. What is flipping is that what `SQL` does is "inconsistent". That is the major sin.
