+<p>When a File-store database is constructed using the <codeph>RDbNamedDatabase</codeph> interface,
+there is no access to the underlying store in order to compact it and recover
+any free space for re-use.</p>
+<p>The <codeph>RDbDatabase</codeph> abstract base class, however, supports
+a compacting interface, the <codeph>Compact()</codeph> member function. The
+class also offers a complementary interface, the <codeph>UpdateStats()</codeph> and <codeph>Size()</codeph> member
+functions, which calculate and report size and usage information.</p>
+<p>Incremental forms of these functions are also offered by the <codeph>RDbIncremental</codeph> class.</p>
