The ease with which I can write SQL statements for my application without having any knowledge about databases or database concepts! This makes it so much easier when you have new requirements coming up along your software lifecycle as well as in daily work life activities!! There are some cases where things do not get translated correctly (as expected) but this happens rarely compared other languages like java/ruby etc., So far none has been able solve problems by using sql only - hence no dislikes yet! We use Mysql at our backend server running all applications including web front end apps built upon AngularJS / Node Js frameworks!!
