SQL

One thing that’s always bothered me is when people pronounce “SQL” as “sequel.”  Where did this come from?  I prefer to spell it out and say “ess kew ell” and I think it probably annoys people who say “sequel.”  I was reading about a new technology called SPARQL, which Wikipedia says is pronounced, “sparkle.”  Then I got to thinking: wouldn’t it be more logical to pronounce SQL as “sickle?”
