a one-to-one relationship from the address attribute of an Employee object to an Address object. To store this relationship in the database, create a one-to-one mapping between the address attribute and the Address class. This mapping stores the id of the Address instance in the EMPLOYEE table when the Employee instance is written. It also links the Employee instance to the Address instance when the Employee is read from the database. Because an Address does not have any references to the Employee, it does not have to provide a mapping to Employee.
