@Rob Sure! Let’s say that I have a user interface where the user chooses their rating for behavior (e.g. How much do you like being on time? Rate between 1-10, 1 being least and 10 being most). The user then selects the value using the slider, say 5. Now, I have another question for that user’s friends where the same question is posed to them How often is User X on time? Rate between 1-10, 1 being least and 10 being most. All these ratings are being stored in a collection where the item is being identified by user X ID and the friend’s IDs. Now, later, I want to display the average rating from user X’s friends as another slider. So, I calculate the average in the backend and display it as a slider on the front end.
