What if something gets an invalid state (eg you expect a record to have
'active = 156' but it's something else).
So in some cases yes you'll need to do a rollback. On the other hand, if
you don't explicitly do a commit, everything is rolled back.
Yes "begin" == "start transaction" and "commit" == "end transaction".
