It would be nice to assign a default value to any
object playing a specific role. Especially if NULL is
a posible situation. It could be a valid default,or a
generic default such as "Not Provided". It should
only be a posibility not a requirement. The default
is applied in a check clause when NULL is received.
This would save time by not having to enter the
column "default" phrase in SQL.
Some situations are really into having defaults in
SQL. Others put them in the application code.
