Quite a few places in the article are making a confusion between the relational model and the SQL language. While the mathematical foundations of the relational model are strong, the shortcomings of the SQL language and its various implementations are known and recognized.

I find the article a bit confusing by not specifying the difference between the relational model and SQL language.

I suggest the author a deeper study into the works of professor Chris Date.
