I am a beginner and I am having a hard time using UML to model a website.I have no idea how to begin with.

I need to use Rational Rose to complete this assignment. Can anyone give me a clue on how to model it?

The assignment is like this:
Model this webiste. Do not worry about Client page or server page.It is simply a website. There is a main page and this page has some links which can bring you to some other webpages.

My question is, how can I show the relationship between the main pages and its subpages? Should I model the main page as a class?

Please shed some light.Thank you very much.
