Some of the more advanced usages of yii here are views with one to many to many views. Normally just one to many is the standard but we take it one stage further. The most advanced reuseable feature is a Report generation motor that is very unusual in that it is done with very little code yet is very powerful. However, the Report generator uses direct SQL calls so it is probably only useable in Mysql.
It is translated into 50 languages!
