    Hi all,
    I was reading thru the Oracle 8i materials and there is a part discussing about when to create an index that I'm quited confused. The materials suggest that in order to avoid locks on child table while performing DML on parent table, we should create index on foreign key. I'm not sure why we have to do this. Can anyone plse explain??..thanks a bunch
