Answer / kebiraj
A foreign key, also called a foreign keyword, in a database
table is a key from another table that refers to (or
targets) a specific key, usually the primary key , in the
table being used. A primary key can be targeted by multiple
foreign keys from other tables. But a primary key does not
necessarily have to be the target of any foreign keys.
