deferred constraints

Hello,

Env: 8.1.6.0.0 on Solaris 2.7

>From reading the docs regarding constraint states, it sounds
like there is no difference in constraint behaviour between a constraint created as "not deferred" vs a constraint created as "deferred" and "initially immediate". Is this correct?

The only difference I can see is that a constraint created as "deferred" can subsequently be altered to other constraint states, whereas a constraint created as "not deferred" cannot.

If the above is correct, is it a good practice to make the default for constraint creation "deferred" and "initially immediate"? The justification for this would be the flexibility of altering the constraint state, should the need ever arise.

How do most of you create your constraints, as deferred or not deferred?

Thanks to any responders.
