                - By default, ``autocommit`` mode is ON (i.e. each DML statement commits the change).
                - If ``autocommit`` mode is OFF, the ``commit`` and ``rollback`` methods are enabled.
        
            - Avoid segfault issue for ``cryptography`` 1.2 in Mac OSX by using 1.1 until resolved.
