Forum Overview :: Global Conflict Blue 2 :: SQL databases weren't really common until the 1980s at least.

[quote name="blackwater"]Systems created in the 1970s like Social Security would not have used SQL. Instead they might have used something like CODASYL, IMS/360, DL/1, GIRLS (later renamed to "Pick"), etc. Pretty much all of these ran on mainframes, as was the style at the time. For example, the US tax system, <a href="https://en.wikipedia.org/wiki/Individual_Master_File">Individiual Master File</a>, is written in assembly language with a dash of COBOL for seasoning. It still does everyone's taxes to this day. I don't know what computer system Musk referring to in his tweet. Perhaps the <a href="https://en.wikipedia.org/wiki/Death_Master_File">Death Master File</a>? In any case, you incorrecting him about a system which he has access to and you don't is one of the most Reddit things I've read in the last 6 months.[/quote]
