Your use of the term "transaction" for a database entity is really
confusing, and will make it significantly harder for others to
understand and work with your schema. It might be worth renaming the
entity to avoid the conflict with the meaning of "transaction" as
"atomic unit of work" as controlled by BEGIN/COMMIT/ROLLBACK .
