Friends,
Continuing on the above..
We have the concepts of foreign keys (either Soft RI or hard RI). It is oftne recommended to go for soft RI since it wont hard stop any insertion of records as well used by query optimizer.
How can one benefit by using RI (used by optimizer) compare to PI definition? Is there any substitute of not opting for PI having composite key and instead going for RI?
Thanks
