Defining Hibernate Inheritance Mappings

Hibernate supports the three basic inheritance mapping strategies:

• Table per class hierarchy
• Table per subclass
• Table per concrete class

• There are not any special different from standard inheritance mapping definition in O/R Mapping Modeling. However, a separate mapping file is generated for each inheritance hierarchy that has a unique mapping strategy. All mappings of subclasses are defined in the mapping file. The mapping file is generated for the root class of the hierarchy.
