In most apps I have a number of enumerations which are used in business
logic .ie if ( job.State == Accepted) or if (service ==
SpecialAirDelivery). Though these change rarely often I am forced to
use a class and a table to handle these rare changes , or have to
compile a new app .
What I would like to do is have a simple table which can be used to
extend a number of enumerations which can be changed on the live system.
I suppose I could use a class with constants, to do the same . Is it
possible to extend this .
Regards ,
Ben
