Friend, unlike the Relational Banks, in SGBD Mongodb there is no concept of relationship and yes, reference.

In your context, you can ship the documents contained in the collection extinguisher with an array historical.

But if you want to have two collections, you can:

In the Historical collection, reference the Extinguisher collection. This way, they will be related by the Object ID (primary key) generated by itself, Mongodb;

I don’t know exactly how Mongoose Node works, but I leave this link in order to help:

Good Luck!
