title: Read Committed vs Read Uncommited if both transaction do not rollback
body: <p>I am trying to understand read committed and read uncommitted isolation levels. I know that theoreticay read uncommitted allows dirty reads and read committed doesn't, but I still can't really understand.</p>

  <p>Considering Figure above, if none of the transactions were aborted then the final result is the same for both read committed and read uncommitted? </p>
