Q. What is scaffolding?

A. Scaffolding is a meta-programming method of building database-backed software applications. It is a technique supported by some model-view-controller frameworks, in which the programmer may write a specification that describes how the application database may be used. The compiler uses this specification to generate code that the application can use to create, read, update and delete database entries, effectively treating the template as a "scaffold" on which to build a more powerful application. Scaffolding was popularized by the Ruby on Rails framework. It has been adapted to other software frameworks CodeIgniter, Symfony, CakePHP, Yii.
