SSChampion, I totally agree and will proceed as necessary to "reasonably" protect the visibility of the data and "absolutely" protect the data integrity. Is there a way to "hide" tables in SQL Server (like there is in Access) and at least require the operator to know to "unhide" them. The point is that if the casual user doesn't know they exist, they won't bump into them and open them out of curiosity. Thanks for your comments and suggestions.
