I have 2 tables: parent and child. One of the fields, which should supposedly be part of the parent table, might occassionaly be different for one of the child table records.
ParentTable
* id
* date
* customer <-----
* reference
* other fields...
ChildTable
* id-parent
* document type
* customer <-----
It is possible that the customer field is not the same for all of the child records. This is a very specific (and strange) situation that might eventually appear in the information system I am developing. I suppose that such a field must be part of the child table even if this case does not appear frequently.
I am writing to ask for your feedback and see if there is another possible approach.
With respect,
Jorge Maldonado
