What is table per class strategy?

Table Per Class strategy is the most logical inheritance solution because it mirrors the object model in the data model. In this pattern a table is defined for each class in the inheritance hierarchy to store only the local attributes of that class. All classes in the hierarchy must share the same id attribute.

What JPA inheritance types can you name?

There are three inheritance strategies defined from the InheritanceType enum, SINGLE_TABLE , TABLE_PER_CLASS and JOINED . Single table inheritance is the default, and table per class is an optional feature of the JPA spec, so not all providers may support it.

What are the types of inheritance mapping in JPA?
