-<h1>Creating Active Record Classes</h1>
-
-<p>
-We need to create two <a href="http://www.pradosoft.com/demos/quickstart/?page=Database.ActiveRecord">Active Record</a> classes, <tt>UserRecord</tt> and <tt>PostRecord</tt>, to represent data records in the <tt>users</tt> and <tt>posts</tt> tables, respectively. Active Record classes must extend from the base class <tt>ActiveRecord</tt>, and must define property names that matches with the field names of the corresponding table.
-</p>
-
-<p>
-To better organize our directories, we create a new directory <tt>protected/database</tt> to hold the class files. We also modify our application configuration by inserting the following lines. It is equivalent to adding the directory <tt>protected/database</tt> to PHP include_path, which allows us to use the classes without explicitly including them.
-</p>
-
-<com:TTextHighlighter CssClass="source" Language="xml">
-<paths>
-  <using namespace="Application.database.*" />
-</paths>
-</com:TTextHighlighter>
-
-<p>
-Instead of writing the classes manually, we will use the <a href="?page=GettingStarted.Wsat">PRADO Web Site Administration Tool</a> to generate the classes for us.
-So we need to modify again our application configuration in the services section like follows:
