The code would potentially be very simple and require very little
maintenance ...If possible... It does not have to be enumerations after
all enumerations have been around for years in C varients (though
slightly different) . A class with constants would achieve a similar
result.
Besides the strong typing it introduces would save many errors you get
from untyped data.
Over the years I have seen so many errors from DataSet["Untyped"] string
or untyped SQL that I think it is worth a look into .. For single value
lookups .
