DatabaseExporter

Exports Open edX data from MySQL database into a spreadsheet. It is possible to export the sheets to a single multi sheet xlsx file or alternatively update a Google Sheet file. On the NAU project it is used the second option. The NAU dashboard, based on Google Data Studio, use that Google Sheet has one of its data source.

This project requires an intermediate database on the same engine of the edxapp openedx database. The mysql database user needs a read grant for the edxapp and all grants for its own database. It produces precalculated tables/materialized views that are 1 to 1 with the xlsx file sheets or each sheet of the google spreadsheet file, each relevant table is prefixed with the DATA_ string.

Those scripts should be run at least once a day, preference after the midnight, so your Google Sheet file always contain yesterday's data in full.

The queries don't have any reference to individual users, and don't have specific identification numbers, like user id, emails or similar data.
