Store 0 by default

Somehow I missed changing the setting for storing 0 values even though I was aware of it. For me 0 values are important (“0 cases” is very different from an “Unknown amount of cases”). I would suggest changing the default setting on installation to store 0 values rather than ignore as this gives the user the option to change this in the future. In my case, unfortunately this data is lost :frowning:

Thanks,

Tom

Hi Tom,

On my side, i think its logical to make it optional(store zero value), because some of the country would not like to see zero`s in their database depending on what they are collecting.

Back to the point, there is a useful functionality that automatically switches store zero value to yes or No

Here is the quickest way to do this go to Data administration------>Zero value storage----Here you can specify which data values may store zero`s or not. if you want all to store zero you make sure all data elements are moved using move all.

Thanks

Andrew

Thanks, Andrew. I understand the option; my only suggestion is to change the default behavior as a more conservative approach. But I guess it depends on the majority of use cases.

Hi Tom,

I understand your concern and I think we could put more emphasis on
this in the documentation. The decision for not storing zeros as the
default option was made with a view to performance and usefulness.
Typically in a large country implementation, 70% of the records end up
being zeros, which will impact performance and storage size
correspondingly. Also, when you aggregate up one level in the
hierarchy or in the time dimension, the significance of zeros
disappear. On the other hand, zeros have some usefulness in seeing
where data has actually been entered. When considering this trade-off
we decided that not storing them would be the most viable default
option. As you know, this is fully configurable.

regards, Lars
