-<p>Use an <span class="bold">Element Collection</span> to define a collection of <span class="bold">Basic</span> objects. The Basic values are stored in a separate collection table. Because the target is a Basic value (instead of an Entity), you can easily define collections of simple values without having to define a class for the value.</p>
