Like Google Notebook

Hi All,

Has anyone tried writing a db structure that would replicate a google notebook heirarchy?

I'm very interested in learning to do this. My knowledge of MSSQL is poor. I had someone else develop a db in MSSQL for me. I'd like to add a similar functionality for my website to that of google notebooks. I don't need the browser plugins and stuff, only the ability to create new notes and sub notes which can have a few fields. For instance.

A - History
----a1.Name: World War 1
----a2.Name: Germany 1918-1945
----a3.Name: World War 2
------a3i.Name: Causes of World War II
------a3ii.Notes: bla bla bl a
------a3iii.Description: These notes are about the causes of WWII
------a3.SubTopic.a1.Name: Hitler's actions prior to WWII
------a3.SubTopic.a1.Notes: notes notes notes
------a3.SubTopic.a1.Description: desc desc desc

I need to develop a max of two level heirarchy for my website to provide my students a google notebook like functionality. I want to develop it for my school's website. Can someone help?
