Dynamic, multi-level navigation

Hello~

After doing quite a bit of Google research, I am not really any closer to discovering a good tutorial for building both the backend and frontend for a dynamic, database-driven navigation system through ColdFusion. I am looking for a start on a system that will, ideally, be able to create both a navigation bar and dynamic breadcrumbs throughout the site. I am not really sure how to structure my database tables, as there are going to be atleast five levels of pages! Any suggestions would be very helpful, thank you!
