[Jason Pickering <jason.p.pickering@xxxxxxxxx>]

Understood, but then this would require a complete overhaul of the
data model. If you look at the data value table, there are separate
keys for dataelementid and periodid, which implies that data values
can be observed in multiple places over multiple time periods (which
may themselves have different durations). This seems logical and
certainly reasonable. Otherwise, there would need to be an association
between a given data element and a given periodicity type, where now
the association is between a data set and a periodicity type. A given
dataset would thus derive its periodicity from a data element, whose
association would need to be specifically set when creating the data
element, and not the other way around.

I would strongly urge that it be best avoided, and or implemented
specifically on a local branch for the SA team.

Regards,
Jason
