Using the same logic, a key/value database is also a graph database?
Isn’t the biggest benefit of graph databases the indexing and additional query constructs they support, like shortest path finding and whatnot?
I think the confusion stems from the fact that we call a database what is really a database management system.
Yes, the author is likely unaware of this. They see markdown files with links, so a graph and the set of those files, so a "database".
