Extended Entity-Relationship Model to tables (subclasses)

In the EER model there are subclasses entities. I was wondering what's the way to implement that in a real SQL Table or if there is any guide that might help me out to understand how to implement entities subclasses into tables that would help. Thanks

Martin Fowler's book Patterns of Enterprise Application Architecture covers solutions for subclassing tables:

• Single Table Inheritance
• Class Table Inheritance
• Concrete Table Inheritance

These correspond to the options in the answer from @spencer7593, without being tied to Java & Hibernate.
