Streaming Ona Data with NiFi, Kafka, Druid, and Superset

Posted:

A common need across all our projects and partners’ projects is to build up-to-date indicators from stored data. We have built dashboards showing project progress and other stakeholder-relevant information in our malaria spraying project (mSpray), drought response monitoring project in Somalia, and electronic medical record system (OpenSRP). Currently we create indicators on an ad-hoc basis, but we are in the process of building a unified pipeline to move data from heterogenous systems into a data warehouse and build indicators on top of this data.

This need breaks down into the following minimal requirements:

  1. Store data
  2. Store queries relative to the data
  3. Retrieve the results of queries executed against the latest data

An inside look at Zambia’s new electronic immunization registry

Posted:

The following was originally written for and posted on the BID Initiative blog. It provides an update on the Zambian electronic immunization registry we’re building with Path, which we introduced in a previous post.

Back in February, I wrote about Ona’s visit to Livingstone, Zambia to work with PATH’s BID Initiative, the nurses in the health facilities, and other project stakeholders to collectively define a health information system that would ease the data collection and reporting burden of the nurses, while at the same time making their data more accessible and useful to them during their work. Coming home from that visit, we had a pretty good understanding of what the nurses’ pain points are, mostly around data entry and reporting requirements. After a rapid and iterative development phase, the app’s first release was launched in April and given to nurses from six health facilities in Livingstone District for the first phase of testing.

Ona at the 2017 ICT4D Conference

Ona will be at the 2016 ICT4D Conference in Hyderabad on 15–16 May 2017. Erick Ngwiri, Director of Client Solutions, will be speaking about Empowering organizations worldwide with collective intelligence.

His talk will focus on how Ona uses geospatial check-ins to improve the targeting and delivery of IRS malaria spraying in over 120,000 homes in Zambia. With geospatial check-ins, we are able to link service delivery to physical structures in OpenStreetMap. Erick will also discuss how we will be applying this approach to child vaccine programmes with the goals of improving coverage and coordination in humanitarian aid.

If you want to meet up with Erick, send him a note at biz@ona.io.
