[Olav Poppe <olav.poppe@xxxxxx>]

Thanks Jason. I realise I should learn R.

I was thinking that it should be fairly simple to make a DHIS app that would let you interact with the DHS API to 
1) select a country
2) select a survey/year for that country
3) select the indicators available for that survey
If importing sub-national data, you would have to have some basic orgunit matching as well (though the number is limited for household surveys), but that's it.

But it does not look like anyone has made that app yet unfortunately.

I image that with household surveys, it would be a matter of < 100 indicators for < 200 orgunits for 2-3 periods, i.e. a fraction of what you are dealing with!

In our current test-scenario (2 dataElements in a dataSet with a categoryCombination of 5 categories) we are currently updating ca. 4 mio dataValues every night in a pseudo-delta mode (reading all data from source, comparing to what is there in DHIS2 already, then only pushing records for creating, updating or deleting dataValues into the api: ca. 150k per night in 1 hour, initial load was 7hrs). We still have to prove, that this is feasible when setting up the first real life dataSet where there will be more categories and more dataElements, thus exploding the number of dataValues.

However, from a data warehouse perspective I'd prefer to have DHIS2 offering some sort of an integrated ETL landscape on the long run, which would also allow to aggregate data from tracker into dataSets, tracker to tracker, dataSets to dataSets etc.

If you are interested, I will share them. Just be aware that they are currently in a very early and rough state and not documented. You'd have to bring along the willingness to dig yourself into kettle and be pain resistant to a certain degree :-)
