From their methodology page (https://db-engines.com/en/ranking_definition), it seems they use:

- Number of search results for each DB's name

- Google Trends

- Mentions in Stack Overflow etc.

- Mentions in Tweets

- Mentions in people's LinkedIn profile

Probably gives a vague idea of popularity of the system, but the measure is otherwise pretty useless.
