Mapping Inheritance with Java Classes
In just about any application, some kind of inheritance hierarchy needs to be mapped to permanent stor-
age. As you saw there are several ways to map the inherence hierarchy. In our mapping,
we’ll consider the following methods:
❑ Table-per-class hierarchy
❑ Table-per-subclass
❑ Table-per-concrete class
