Hi All,

As per Hibernate ref-guide, there are two sub-strategies under Table per Concrete class strategy:
1. Table per concrete class with union subclass
2. Table per concrete class with implicit polymorphism

With union subclass it is mentioned that you will need a separate table for the super class if it is not abstract. Is it the same case with the second sub-strategy Table per concrete class with implicit polymorphism. That is if the super class is not abstract, do we need a separate table? Any links / references to documents will be helpful.

Thanks,
