Hi Richard.  I am so pleased with your courses!!  I've been fumbling around with Access for a 3 years trying to make things work, reading the Step by Step and reading forums but, your courses are providing some of the missing links.  
I do have a question about Normalizing tables.  You show creating a seperate table for a single field that is duplicated in the existing table.  Is there really any benefit to creating a seperate table (which becomes a child) if there is only one field?  I'm not understanding that.

Do you have the example given?

Security is one I can think of, say having CreditInfo in a separate Table which you then link to Customer and only let certain people see that info.
