I am trying to define an ORM mapping with more complex rules than simply connecting one attribute with another.
For example, I have a class model like
- Juristic Person
Both Person and Institution are Juristic Persons, so Juristic Person is a generalization of them.
In the DB, all is in one table: person, institution and general jur. person data.
There is a flag “is_person” in the DB to say that the entry is a person and not an institution.
Now I want to do two things:
- define somehow that the DB data goes to Person if the flag is set and goes to institution if not
- map all general attributes to my class juristic person, because person and institution are meant to inherit these attributes.
As for 1) - I see no way how I could do this - is there any?
As for 2) - VP seems bugged. When I map the attributes like I want, somehow all my classes in the ORM diagram get to be called “juristic person”… how is that possible? Is this a feature I do not understand?
