Answer / jayasree

A foreign key links two tables T1 and T2 by assigning
fields of table T1 to the primary key fields of table T2.

Table T1 is called the foreign key table (dependent table)
and table T2 the check table (referenced table). The pair
of fields for the two tables must have the same data type
and length. One field of the foreign key table therefore
corresponds to each key field of the check table. This
field is called the foreign key field.

A foreign key permits you to assign data records in the
foreign key table and check table. One record of the
foreign key table uniquely identifies one record of the
check table using the entries in the foreign key fields.

When an entry is made in the check field, there is a check
whether the check table contains a record with the key
defined by the values in the foreign key fields. If this is
so, the entry is valid. Otherwise the system rejects the
entry.
