                <li> dataIOServer, with the persistent data. \c IO() method returns
                a pointer to the persistent data.
        </ul>
        <li> Any transient data can be recovered using the \c getData() method.
        <li> the \c update() method, update any transient data.
        <li> The persistent server could be replaced. The user should the typedef dataIOServer 
        to her/his defined <b>persistent data server </b> (i.e for ROOT, we use dataIOROOTServer).
