RE: Primary & Foreign key constraints

Rufus,

if you try to enforce RI at the app level .. u are looking in the face of increased IO hits as you try to manually force RI rules.. may also lead to funny situations (mutating/constraining) as you start playing with triggers trying to accomplish the same. thats all my brain cells allow me to write at this point :-((

Hi Guru's,

Will any one tell, if there is any specific advantage if we don't have primary & foreign key constraints at database level. In one of our major applications I have seen, they do not have primary & foreign key constraints defined at database level, but handled at the front end level. Can anyone tell what could be the merits if any ?

TIA,
Rufus.
