I'm new to mongoDB, and I wonder how I can translate tables relations in MongoDB.

For example in my MySQL base, I have two tables : Manager and Employee.

```
Manager {
  name: String,
  ID: Int Primary Key
}

Employee {
  name: String,
  ID: Int Primary Key,
  Manager: int Foreign key (Manager.ID)
}

```

I would like to know what is the correct way to implement this with MongoDB.
