Answer

Brief Explanations:

In a relational database, a foreign key is a field (or set of fields) in one table that refers to the primary - key of another table, establishing a link between tables. It is not related to security keys for foreign - located databases or data, nor is it a unique identifier within its own table (that's a primary key).

Answer:

a field in a table that links it to other tables in a relational database
