Dear Abyota*,* I'm trying to follow your working on Patient module so that I've got some questions wanna ask you like this: * Creating attribute group*

At the same I would suggest for a restriction of putting > an attribute only in one group - otherwise it will be ugly down the road. > Because, for example in your case of permanent and temporary address > > Temporary Address Group > > - street > - village > - province > - ... > - .. > - phone > > then Permanent Address Group arrangement of the same attributes > > - street > - village > - province > - ... > - .. > - phone > > will create a problem in fetching the values ... otherwise we need to also > store attribute group id when persisting attribute values.....I prefer to > append something like "temp" and create slightly different attributes than > persisting attribute group id when storing attribute values - I don't know > others can comment on this and come up with a better suggestion. > > You suggested that the attribute group and attributes which have a relationship as one to many, didn't you? But the approach in Dataelement management with the relationship is many to many. Btw, you said also that *"otherwise we need to also store attribute group id when persisting attribute values" *but its seemly opposite to *"I prefer to append something like "temp" and create slightly different attributes than persisting attribute group id when storing attribute values"*. Or I'm misunderstanding your idea? On the other hand, Can you please explaining to me more about *PatientIdentifier *and *PatientIdentifierType*. What are they used for ? Thanks ! -- Hieu.HISPVietnam Good Health !
