Manager: I'm concerned about one of the figures on this report
Deputy: Which one?
Manager: 4th column.
Deputy: Which line?
Manager: Hang on while I count down from the top.
Deputy: Hope you don't mis-count then.
Manager: Aye, you don't wanna be chasing up the wrong thing
Deputy: Can't we just put line numbers on these reports like the old
system had?
Manager: No, Celko said we must go back to the basics of an RDBMS
Deputy: Ah, so you could identify the line to me without counting, just
tell me what's unique about it.
Manager: I could, if I knew WTF was unique about it, you should know us
management types have absolutely no technical knowledge.
Deputy: So these management reports were written for....
Manager: Aye, technical people to read.
