Hi, while JDO inheritance strategies offer more flexibility in general than JPA, there appears to be one situation not catered for; namely the JPA strategy of TABLE_PER_CLASS.
I'd propose adding a further JDO strategy of "complete-table" which, when specified on a class means that that class has a table providing columns for all fields of that class and any persistent superclasses.
