Re: ER Diagram of a schema

You cannot create ER diagram of a schema, you can create only server(data) model diagram
If you want to create this diagram yourself, ie on paper, using some graphic tool like M$Word, Corel or M$Paint then you will need to use at least such data dictionary views like

{all/dba/user}_tables
{all/dba/user}_tab_columns
{all/dba/user}_views
{all/dba/user}_constraints

To be more seriuos I would like to suggest to use some more or less specialized tools like
Oracle Designer
Visio
Erwin
Grade (www.infologistik.com)

Oracle Designer and Visio can connect to Oracle and create server model diagram from database. Oracle designer provides such a possibility like table to entity rettrofit which creates ER diagramm. Of course it could be and usually IS different than original one. I don't know about Erwin, but Grade cannot make diagrams from databses. I mentioned it just for info and I think it was rather interesting tool but cannot be in the top today.
