        <h1>Rollback Strategies</h1>
        <p><a href="../../transparent_persistence.htm">Transparent Persistence</a> makes
development faster and more convenient. However without a clear understanding
of what is happening under the hood you can easily get into trouble. Transparent
Persistence is triggered by commit call and with rollback the changes are
simply discarded. But is it really all that trivial?</p>
