	If 1GL = machine languages, 2GL = assembly languages, 3GL = high level
	programming languages, and SQL cannot be classified as a 4GL,
	then where exactly do data definition and manipulation languages
	like SQL fit in, in this hierarchy? Surely SQL cannot be classified
	as a 5GL, i.e., at a level higher than the current definition of 
	a 4GL. Maybe the current 4GLs should be called 5GL and languages
	like SQL should be called 4GL.
