<h1><a name="kanchor99"></a>Best Practices</h1>
<p>This topic is a collection of best practices for db4o.</p>
<p>db4o doesn't have any support for limiting the result size or skipping objects in the result set. You can do this on top of db4o with little effort. <a href="best_practises/paging.htm" target="" title="" alt="" class="MCXref">See "Paging"</a></p>
<p>How should you scope the lifetime of an object container? See this guide-line: <a href="best_practises/lifetime_of_a_objectcontainer.htm" target="" title="" alt="" class="MCXref">See "Lifetime Of An Object Container"</a></p>
<p>Deleting object is always a delicate process. <a href="best_practises/deleting_objects.htm" target="" title="" alt="" class="MCXref">See "Deleting Objects"</a></p>
<p>If you upgrade to new major db4o version you should do these steps to update the file format. <a href="best_practises/updating_db4o_version.htm" target="" title="" alt="" class="MCXref">See "Upgrade db4o Version"</a></p>
