Newbie Visio to Oracle question

[jerry8989]

I'm very new to Oracle 10g and Visio 2003 Prof.  I just want to diagram a schema/db from Oracle. 

1. How can I connect to the schema/db through Visio?
2. I want to make sure by doing this I don't change anything on the schema/db.  From what I read that reverse enginerring might make changes to some of the tables.

Just want a simple diagram showing all the tables and how they link.

Thank You all for any help

You might need to find someone who uses Oracle databases but I've just had a look and Oracle 10 dates from 2003 so I think it's unlikely that Visio 2003 will be able to read it.
