<p>One of the most widely used platform independent formats of data exchange today is xml.</p>
<p>Db4o
does not provide any specific API to be used for XML import/export, but
with the variety of XML serialization tools available for Java and .NET
(freeware and licensed) this is not really necessary. </p>
<p>All that you need to export your database/query results is:</p>
<ol>
<li>Retrieve objects from the database.</li>
<li>Serialize them in XML format (using language, or external tools, or your own serializing software).</li>
<li>Save XML stream (to a disc location, into memory, into another database).</li>
</ol>
<p>Import process is just the reverse:</p>
<ol>
<li>Read XML stream</li>
<li>Create an objects from XML</li>
<li>Save objects to db4o</li>
</ol>
<p>Let's go through a simple example. We will use .NET XmlSerializer. (You can use
any other XML serialization tool, which is able to serialize/deserialize
classes).</p>
<p>First, let's prepare a database:</p>
