interface TransactionTarget

Whatever a transaction statement is carried out against.

A statement read out of SQL says which of the six things it is, and carrying that out is someone else's work. Saying only that much here lets the statement stay something read out of text: it hands itself to a target without naming what keeps the transaction state, and without giving up the operation and savepoint name it holds.
