Normalization depends on how the data will be used. For instance in the
contacts database you want to enter a name only once. What you have looks
fine but it makes an assumption: Each address has only one contact and each
contact only one address.
I'm not sure why you want City, State and Zip in other tables. Granted,
there are programmitic advantages to doing this, like being able to present
a list of cities/states for an entered zip code. If your users will just
read or data entry is not important then normalizing those values can be a
pain and I think it's overkill.
Note: If you want to limit the users to entering valid state codes (a list
which hasn't changed in 15 years), just code that into Code Charges
validation routine or use a list box with a hard coded list.
