Need table relationship Diagram for Active Directory

[Lea]

I am working on a school project based on VB.NET and
Active Directory. In my project documentation, because I
used Active Directory as my basis for data, I must show an
entity relationship diagram or at least a data dictionary
showing field relationships between AD tables.

Does Microsoft have a database dictionary or something
that shows relationships of the various tables for Active
Directory?

The document located at the following link has detailed
information, but nothing that shows actual one-to-many
relationships between the various tables in the active
directory.

If you could point me in the right direction, I would
greatly appreciate it.
