Sure but I use GraphQL as middleware when fetching from elasticsearch, or redis, or flat files. It is not something you hook up directly to your database, it's a way to help define an api for your application.
Most of the time, in my app, resource names do not even correspond to single tables or backend data structures but are simply presented that way for ease of use for external consumers.
Subjectively, Implementing it feels more like old school COBRA than REST or SQL.
