How about: s/(row|tuple)/record/

A "record" is a much less theoretical/mathematical term that I've had
good success in using when describing basic table theory to lay
people. Seems easier to grasp on the uptake than a row (rows are
confused with columns if you're not familiar with databases, math, or
matrices. "Do rows go vertically or horizontally?") or tuple
(heavily mathematical term or term used in DB theory, but no where
else). A record, on the other hand, is something that everyone has a
conceptual picture of. -sc
