I think that whether you use one table or three the processing overhead will
be the same - you will still need several seeks which will take the same
amount of time whether they are on one table or three.  A single table will
give you more flexibility and will be easier if the user wants to enter a
code directly.

Can't help on the Gui I'm afraid.
