+This package contains classes that provide compatibility to a range of RDBM platforms.
+<p>
+The <code>Platform</code> interface provides callbacks that allow to get
+RDBMS Platform specific information whereever neccessary.
+
+<p>
+The class <code>PlatformDefaultImpl</code> implements <code>Platform</code> and
+provides default implementations of all methods.
+
+<p>
+For each supported Platform <code>Xxx</code> there is a class <code>PlatformXxxImpl</code>
+which extends <code>PlatformDefaultImpl</code> and may override the methods of the
+baseclass.
+
+<p>
+The factory class <code>PlatformFactory</code> can be used to create <code>Platform</code>
+instances.
