Hi all,
This is a fundamental concept in RDBMS: the use of foreign keys in
database design.
I'd just like to poll the community here, on whether it is a best
practice, or practically essential to 'link' related tables by use of
foreign keys.
For myself, I usually do all the validity checking when adding a new
record that references a record id from another table. I understand that
this may not be efficient because it becomes 2 database calls (and db
calls are expensive in high-load environments).
What are the advantages/ disadvantages in using foreign keys? In MySQL,
this means one cannot use MyISAM. Do you place a lot of triggers as well?
Thanks.
