I'm not sure what you mean here... you need a User class if you want 
User objects...

All GOODS access.  What it does is set up one transaction per HTTP 
request, and rollback and repeat the request any time the transaction 
fails.  It's a very simple but generally useful default policy.

I don't see why you'd need more session variables, but maybe I'm 
misunderstanding the question.  All access to GOODS data goes through 
the root object of the database.  This will likely have items in it 
like 'Logs' and 'LogTypes'.  So you might have a method on your session 
like this:

	^ self db root at: 'LogTypes'

But I don't think you'd have an instance variable just to store that.
