This illustration shows an example of explicit mapping for a one-to-many bean relationship. There is a table row on the left labeled "EMP" with the following column heads: "PK:EMPNO", "ENAME", and "SAL". On the right, there is a table row labeled "PHONE" with the following columns: "PK:AUTO_ID", "PHONE_NO", and "EMP_NO". There is an arrow pointing from the "EMP_NO" column in the "PHONE" table to the "PK:EMPNO" column in the "EMP" table.
