Custom Types - Enums

[nick_georghiou]

Hi,
I have seen a couple of previous posts (one about Sql Types, and one
about constraints) which are similar to this topic. Ideally it would
be nice if Custom types could be created or a types list could be
imported.

The issue that I am finding is that although I can use constraints to
define an enumeration e.g. create an attribute that is of type Int and
then have a constraint e.g 1, 2, 3, there is no context provided for
the constraint values (although I realise I could use strings in this
case...). But more importantly, there are instances where the same
enum is required as a type for more than one attribute, which results
in duplication of the constraint and the overhead of maintaining the
constraint in multiple places if it needs to change.

I have considered modelling some enums as entities but this doesn't
really work either. Does anyone have any other suggestions or
workarounds?

(and notes for attributes would be good to :-) )

Regards,
Nick
