There is no need to check for transactions at the end of every user input, as the vast majority of input will not issue transactions. This implementation can also hide where changes are made without an appropriate transaction commit, as a future unrelated input would issue the commit instead. Instead, commit transactions in places where changes are made or are likely to be made.
