It is possible to adapt OpenJPA to access a non-relational datastore by creating
an implementation of the
<a xmlns:xlink="http://www.w3.org/1999/xlink" href="../javadoc/org/apache/openjpa/kernel/StoreManager.html" target="_top"><code class="literal">
org.apache.openjpa.kernel.StoreManager</code></a> interface. OpenJPA
provides an abstract <code class="literal">StoreManager</code> implementation to
facilitate this process. See the <code class="literal">org.apache.openjpa.abstractstore
</code> package <a xmlns:xlink="http://www.w3.org/1999/xlink" href="../javadoc/org/apache/openjpa/abstractstore/package-summary.html" target="_top">
Javadoc</a> for details.
