Map the entire inheritance tree to a table & map each class to each table

There are two classes: skiller and sales. They all inherit from the employee class. Now we need to map them to the database. · Write skiller and sales classes to inherit the sub-employee class. The class has the corresponding attributes and the gets and sets methods. Write the employee. HBM. the XML file is as follows (main code)

<Property name = "canonical"/> </subclass> </class>

<Class name = "employee"> <ID name = "ID"> <generator class = "native"/> </ID> <joined-subclass name = "skiller" table = "skiller"> <key column = "emp_id"/> <property name = "skill"/> </joined-subclass> <joined-subclass name = "sales" table =" sales "> <key column =" emp_id "/> <property name =" canonical "/> </joined-subclass> </class>
