<h1>Pluggable Storage</h1>
<p>Pluggable nature of db4o <span class="MCPopup"><a href="javascript:void(0);" class="MCPopupSpot" onclick="FMCPopup( event, this ); return false;" MadCap:src="../storage.htm">Storage<img style="border: none;margin-left: 5px;" src="../../../SkinSupport/ExpandingClosed.gif" MadCap:altsrc="../../../SkinSupport/ExpandingOpen.gif" class="MCExpandingIcon" onload="if ( typeof( FMCPreloadImage ) == 'function' ) { FMCPreloadImage( '../../../SkinSupport/ExpandingOpen.gif' ); }" /></a></span> adapters allows you to
implement any persistent storage behind the database engine. It can be memory,
native IO, encrypted storage, mirrored storage etc.</p>
<p>The implementation is guided by 2 interfaces:</p>
<p MadCap:conditions="Global.Primary:java" />
<p MadCap:conditions="Primary..NET">
<p>.NET:</p>
<p><code>IStorage</code> and <code>IBin</code></p>
</p>
<p MadCap:conditions="Global.Primary:net" />
<p>Storage/IStorage interface defines the presence of this
particular storage implementation and Bin/IBin implements actual physical access
to the information stored. To simplify the implementation db4o provides
StorageDecorator and BinDecorator classes with the base functionality, that can
be extended/overridden.</p>
<p>To sort out the details of the implementation let's look at
an <a href="pluggable_storage/logging_storage.htm">example</a>.</p>
