-The configuration above shows that we are adding to our application a module whose class is specified in the namespace format as System.Data.ActiveRecord.TActiveRecordConfig. Through this module, Active Record will automatically establish a DB connection by using the connection information given in ConnectionString.
+The configuration above shows that we are adding two modules to our application. The TDataSourceConfig module is configured with the connection string sqlite:protected/data/blog.db which points to our SQLite database. This connection is used by the TActiveRecordConfig module which is required by Active Record.
-One may set up two or more DB connections in the application configuration. For more details, see the Active Record Documentation. And of course, one may also explicitly create a DB connection in PHP code using the TDbConnection component in PDO.

Creating Active Record Classes
-We need to create two Active Record classes, UserRecord and PostRecord, to represent data records in the users and posts tables, respectively. Active Record classes must extend from the base class ActiveRecord, and their properties must match exactly to the fields of the corresponding tables. To better organize our directories, we create a new directory protected/database to hold the class files.

+To better organize our directories, we create a new directory protected/database to hold the class files. We also modify our application configuration by inserting the following lines. It is equivalent to adding the directory protected/database to PHP include_path, which allows us to use the classes without explicitly including them.

Instead of writing the classes manually, we will use the PRADO command line tool again to generate the classes for us.
