Recently I was asked question in the interview that you have given a room, explain all the coordinate systems by using the objects in room. Explain what matrices transforms you will do for converting into different coordinate spaces.

So what's your question? ;)

For some good reading on this, see the "Viewing" chapter in The OpenGL Programming Guide (http://www.amazon.com/OpenGL-Programming-Guide-Official-Learning/dp/0321773039/).
