What interesting problems have you solved / are solving with the help of graph databases?

Question

NoSQL

Interested in any answers and ANY experience. Just tell without formalities - how, why and why.
And yes, I do not ask why such a database. Now I'm picking Neo4j myself and I'm happy as a child with what I can get from it. I would like to look at such tasks from a different angle (from the height of the experience of professional comrades) :) maybe there is something to draw on?

Answer 1

I solve this - sasdate.ru/. There is a brief description and training videos.
Actually, mysql is installed there, because. it was necessary to use the standard set of services provided by the hoster (this is not only related to the specified hoster). But the database and api are made in such a way that, in essence, data storage is a graph structure. My deep conviction is that graph databases are the future. How they will compete in speed is another matter, but this is the business of the database developers. Interested only in the principle of data storage.
