Can I create a second entity that only maps a subset of the most commonly used attributes? Is there anything I should consider? Yes, you can map two or more entities to the same database table. If you want to map the same database table to two entities, you should create a simple inheritance hierarchy. The superclass, in this example a class called AbstractAuthor, should be abstract and contain all attributes that are shared by both entities. You should map it as a mapped superclass so that it is not an entity itself.
