Multiple assignment, or more correctly dbvar assignment.
(dbvar = [the] database variable)
Plus the use of local/temporary/database relvars to allow sets of data can be built up over time, then be added to the 'main' database in one single multiple assignment.
Plus any 'locking' functionality required via database constraints.
But do note that I did not say you don't need transactions under the covers, of course we do. Just that database *users* should not be exposed to such damaging complexity.
