And how many angels dance around the head of a pin?

The person who corrected you could themselves be corrected.

• Table = Relation

• Row = Tuple

• Column = Attribute

• Domain = Data Type

See here.

I worked for an airline and the word "flight" could be used in three different ways depending on whether you were talking to pilots/attendants, engineers or marketing.

• pilots/attendants: a "flight" was out and back from base.

• engineers: take and land, could be test, repair, training.

• marketing: a six month (on-season/off-season) series of "flights" from/to a given airport.

The spreadsheet analogy is more than good enough for 99.99% of cases, even in reasonably technical speech (unless one is a professor of relational algebra). Does the person who corrected you use the word "whom" correctly? 99.99% of people don't and it really doesn't matter.

And how many angels can dance around the head of a pin?

I worked for an airline and the word "flight" could be used in three different ways depending on whether you were talking to pilots/flight-attendants, engineers or marketing.

• pilots/attendants: a "flight" was out and back from base (i.e. two take-offs and two landings),

• engineers: one take-off and one landing, could be test, repair, training (i.e. one airport back to the same airport) or a "leg", i.e. one airport to another - what "civilians" would normally call a flight, as in "I'm catching my flight home tomorrow"),

• marketing: a six month (typically on-season or off-season) series of "flights" from/to a given airport in the context of a contract.
