Hi all
hopefully a quick question about horizontal mapping...The documentation provides the following
example...
Person
v
v v
Employee Customer
It would seem that the "id's" of the Employee and Customer tables are unique for both tables, so I
was wondering how the situation of a person being both an Employee and a Customer is handled?
Are two entries created, one in each table with the same id or am I completely on the wrong track
and that would be a case for Vertical or Single Table Mapping?
Thanks
Paul Mathews
