Working with Database
Yii provides powerful support for database programming. Built on top of the PHP Data Objects (PDO) extension, Yii Data Access Objects (DAO) enables accessing to different database management systems (DBMS) in a single uniform interface. Applications developed using Yii DAO can be easily switched to use a different DBMS without the need to modify the data accessing code. Yii Active Record (AR), implemented as a widely adopted Object-Relational Mapping (ORM) approach, further simplifies database programming. Representing a table in terms of a class and a row an instance, Yii AR eliminates the repetitive task of writing those SQL statements that mainly deal with CRUD (create, read, update and delete) operations.
Although Yii DAO and AR can handle nearly all database-related tasks, you can still use your own database libraries in your Yii application. As a matter of fact, Yii framework is carefully designed to be used together with other third-party libraries.

Thank you.
First of all, congratulations for this very improved version of prado. I haven't looked deeply thru the tutorial yet, but I can see an error. I'm using firefox on ubuntu linux and as I change the language button on the top of these pages, nothing happen. Is it normal?
