If that plan duplicates data then I would not do that. In any Access db that contains proprietary/private information, you design to prevent access to that information through tinkering in tables. Only forms and reports serve up information, and they are based on queries, not tables. Those queries cannot be viewable by way of poking around in the nav pane and you limit access to data/forms/reports based on user profiles/levels.
The more we hear silence, the more we begin to think about our value in this universe.
