Hi Knut,

 

Although I can see that program indicators can be helpful it has limited use in the context of interoperability between DHIS2 instances. In South Africa we feel that Survey type instances should be kept separate from Routine Health data collection and as such collect event or tracker data for surveys and would want to set up aggregated data elements in the system which populates with a stored aggregated data value which we export/synchronise with the routine HMIS system e.g. 

Patient satisfaction survey rate = No of surveys conducted/No of facilities

Patient satisfaction rate = No of satisfied responses/All responses

 

It is true that these aggregated elements can be populated with a function called via a sql view or cron job but not the most ideal. 

Up to now I have not figured out how to set up an indicator which counts if there was any surveys done in a specific period by adding a program indicator due to the limited amount of mathematical calculation formulae allowed in the Program Indicator engine. 

 

This said I must say that we don’t have much confidence in the accuracy of the Aggregation Query Builder as it is at the moment because there seems to be a ceiling limit on how many values can actually be inserted by running a scheduled or manual aggregation process and the simultaneous initiation of scheduled Aggregation Query builder and Analytics are problematic. For this reason we are checking the output of the Aggregation Query builder at this stage and when not entirely confident that it produces reliable results we are using functions instead.

 

Regards,

Subject: Re: [Dhis2-users] Aggregation query builder details

 

Hi Knut

 

We actually use Aggregation query builder to a large extent to get aggregated data. Exclusively, all our data is captured through Event capture, and we aggregate it through Aggregation query builder, so that the aggregated values can be shown in datasets as well as Pivot tables.

Also, using Pivot tables with data elements is easier for the end users since they there is flexibility to can slice and dice the data with categories under Pivot tables. 

 

Don't you think aggregation with only program indicators will limit the use of categories and therefore easy visualization under pivot tables.

 

Thank you

Hi Nami,

 

Which version of DHIS2 are you working on? We are phasing out the aggregation query builder in favor of program indicators.

Hello,

 

I want to create an Aggregation query builder details as sum of data element value I put everything but it comes to Data element for sum/average/min/max * and try to select I can’t find anything and this field is 

 

mandatory and the data aggregator data element and tracker data element both has sum aggregator 

 

Any idea about this 

 

Thanks in advance
