Moreover PRADO was also difficult to customize. This is where development by Yii framework comes in handy. Yii even has a provision to store user-contributed components in its extension repository.The development stage took 10 months and finally it on October 2008 that an alpha version of Yii was released. But it was on December 3, 2008 that the full version was formally introduced in the market.Why Yii is Good for You?1. Easy to Install
