With respect, who actually feels at home with SQL?
It's about the most alien and obtuse language I've ever had the misfortune of encountering, and in that category I rate it worse than COBOL, FORTRAN, Assembly, C, Prolog, Sendmail re-write rules, BASH, and every other language I've ever encountered and had to use, but which I cannot recall at the moment.
It tries to provide ergonomic data munching of various formats, but using a sql interface, which most will probably feel immediately at home with.
