Hibernate domain model object representation

Hibernate ORM
1

Hi everyone,

  1. What does the mean of ’ The term domain model comes from the realm of data modeling’ as mentioned on the Section 2 in hibernate user guide?
  2. Entities are mapping to relational data
    Entities are created based on the data model. Is that correct?
  3. Then Domain model consists of boundary, controller and entity objects. So is that entity objects are similar to Entity objects?
  4. But we don’t define entity classes based on the domain model, but the data model. Is my understanding correct?
  5. Then, why does it say object model to relational model. What is this object model? Domain model entity objects or what?
  6. Can someone say the relationship between domain entity model with the relational data?

Appreciate your support in advance.
I was wasting my time to find out this
