Scaffolding is a meta-programming method of building database-backend software applications.

Scaffolding is a meta-programming method of building database-backend software applications. It is a technique supported by some model-view-controller frameworks (like Ruby on Rails, CodeIgniter, Spring Roo among many others) in which the programmer may write a specification that describes how the application database may be used. Some tool uses this specification to generate code to cover basic CRUD (Cread Read, Update, Delete) functionality, effectively treating the template as a scaffold on which to build a more powerful application. (View Wikipedia definition)

In many cases this scaffold can and has to be modified if we want to achieve more complex functionality and it's a reason why this feature is not recommended in complex sites.

Recently the term scaffolding has also been used for the use of pre-defined layouts or grids in CSS frameworks like Twitter-Bootstrap.
