I wrote a document about my experience exporting some (fake) COVID-19 data from CommCare to a Postgres database and charting that data using Apache Superset. If you are building a reporting pipeline but prefer not to use the Tableau or Power BI tools that are already integrated with CommCare, you may benefit from the lessons I learned.
The notes are in a separate document because they grew too long to be a good forum post. However, please send any questions to the forum because many other people besides me may be able to answer them.
