-DataHub can use Dgraph as the graph database in the backend to serve graph queries.
-An alternative to Dgraph for that purpose is [Neo4j](../neo4j).
-
-The [Dgraph image](https://hub.docker.com/r/dgraph/dgraph) found in Docker Hub is used without any modification.

-## Dgraph UI Ratel

-You can use the cloud hosted Dgraph UI [Ratel](https://play.dgraph.io/?latest#) to connect to your Dgraph cluster,
-run queries and visualize your graph data. Point the UI to [http://localhost:8082](http://localhost:8082).

-## Developer Notes
-The [DataHub CLI quickstart](../../docs/quickstart.md) command fetches these YAML files from DataHub's GitHub master.
-This means, files referenced by earlier releases of DataHub CLI must not be deleted from this directory in order
