<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>
