Hi! We automatically source the full list of open-source databases from https://dbdb.io/ and calculate daily updated metrics based on Github data. Check the full list of open-source databases on our website https://runacap.com/data/db-index/. All of them was included in analysis.

In dbdb.io there is no mentions of any github repos (https://dbdb.io/db/sqlite).

I think it's just a society page about what the "right kind of people" want people to think the "right kind of people" are doing -- it passes for "insightful" on Medium.

Other people use: PostgreSQL, MySQL, MongoDB, ArangoDB, OpenLink Virtuoso, Neo4J, Berkeley DB just to say a few.
