Some of us do mind, as it makes discussions on the subject at hand
("databases") very confusing: "Relation" is THE essential concept in RDBMS,
and it is certainly not what you mean by your use of the word.
I might suggest that you think/say "relation" when you say "table", and say
"relationship" when you think "relation" - this would be closer to the
concepts....
Better yet: learn the basics of the topic you talk about! You may have some
useful ideas to share, but they are obscured by wrong arguments, based on
either lack of knowlegde or wrong use of terminology.
No spam intended!
