In Kawamata's article "The derived category of toric varieties", he constructs exceptional sequences (ie. a special generator set of the derived category) for toric varieties. This can be done inductively by using the toric Minimal Model Program. Actually, Kawamata's method needs a generalisation of varieties to so-called orbifolds - a special form of stacks. In this talk I want to give an overview of this article. I will focus on the point, why orbifolds enter the picture, and how they can be described in the toric setting.
