What is a tuple

Also known as a “Record”, or a “Row”.  The word “tuple” is used because it can refer to a row returned as part of a result set as well as a record in a table.  Strictly speaking, a row returned from most queries is not a record, as that row does not exist in permanent storage anywhere …. it is created by the query.  Hence, “tuple”.
