create db, mount stages, sql.bsq, catalog.sql

Hi All,

I know it's been a very long time since I've posted. Mostly I'm just lurking,
and reading these days.

I'm working on a presentation for Collaborate 2007. I'm illustrating a very

basica CREATE DATABASE, with only a few options. I want to illustrate the state of the data dictionary when:

1. startup nomount
2. after we have run create database (sql.bsq does what?)
3. after we have run catalog.sql

I've been digging around myself, and for instance at stage #1 v$session, and v$parameter and so on are available. In face many v$ tables such as v$tablespace, and v$datafile are available, but return an error at this point
because the db isn't mounted. After stage #2 those v$ tables work properly.

Does anyone know of a good discussion of this, or thorough documentation on it.
I would like to cover it a little better than my own investigations might.

Thanks in advance,
Sean
