Complex hibernate mapping

Hi everyone,

My application's entity model isn't equal the data model. In some cases, an entity is represented by TWO tables. In others, some fields of a table are mapped in a class and the others, in another entity.

By now, i am using JDBC in the persistence, but I intend to change it to Hibernate. Does anyone know if it is possible to these kind os mappings?

Examples:
- ONE entity represents TWO TABLES:
The entity BeanActivity refers in some cases to table ACTIVITY1 and in other cases to table ACTIVITY2.

-Some fields of a table are presented in an entity1 and the other fields, in entity2.

In the current stage, it's impossible to remake the data model!

I am not asking the solution for this problem. I just wanna know if it's possible with hibernate.

Thanks a lot, Guilherme

Use logical entity names, read a book.
