> SQL Server allows the creation of user defined types.
> These allow (I think ... I've never used SQL server) a user
> to define a new type (much like C typedef) that:
>     a) Has an underlying type (e.g. Number, Text, ...) and
>     b) Constraints (must be in range 0 to 100)
> The schema can then use this user defined type where
> it normally would require copy-and-paste of the type and
> the constraints.
> It seems that hibernate could easily add this capability even
> to databases that don't support it because the SQL generation
> could perform the copy-and-paste itself.
> The benefits seem pretty obvious:
>     a) A type can be changed in one spot, if necessary
>     b) The 'same' types become obvious ... all ints aren't
>          the same 'type' anymore ... which helps with
>          comprehension of the schema (which joins make sense ...)
>     c) The constraints that *should* be the same, *ARE* the same.
>         This helps with consistency.
