Sometimes the business requirements are that you have a master detail ( a 2 dimensional array in O/R), or a many to many.O/R is not always needed. Sometimes you just want to work with a relational master/detail (ie, next row(); next row();).
My concern is not to have to think in term of (for example) Primary Key/Foreign Key or Conposite Key...
RowSet.next() can be easily overridden.
Relational algebra can explain some business easily, that O/R can't.

This is too much low level for me. And some programmers I talk
to really don't care about my DB model.
That's why I am looking for tools that provide an abstract layer between
DB and business objects worlds.
I think O/R is exactly that. I don't see exactly what JDO is. An API by Sun for those kind of
problems?
