<h1 class="topictitle1">Ensure data integrity</h1>
<div><p><span class="keyword">iSeries™</span> provides
several different integrity measures, including constraints, trigger programs,
and commitment control.</p>
<p>Protecting your database against inadvertent insertions, deletions, and
updates is accomplished using commitment control, constraints, and triggers.
Constraints basically govern how data values can change, while triggers are
automatic actions that start, or <em>trigger</em>, an event, such as an update
of a specific table.</p>
<p>See the related topics to learn about different integrity measures.</p>
