As we know ERD diagram is very useful for relational databases. Which Diagram is relevant for Non relational database ? can ERD be also used?

My take on it:

If there are entities you need to define relations on, you can still use ER Diagrams for the sake of documentation.

The choice of using a non-relational might be an implementation detail,then.

Use Case, Class, Structure, Collaboration, Sequence etc. Currently using all of those diagrams for my Java games development project. Hope that helped! Good luck
