example database setup

I would like to set up a zope/database interface (using Postgres 7.4) with
the following properties:
- multiple users each with their own id and password - accessed via zope
- they will enter and access their own data via zope to Postgresql
- any specific user will not be able to see another user's data
- the user will not manage his/her web-page

I have Zope 2.6 and Postgres 7.4 set up and working with each other. Also,
have a few ideas on how to do this, but thought it would be easiest if there
were some similar examples out there to look at. Any suggestions from
anyone, on anything that might be similar to the above task? I'm sure this
has been done many times.
