MongoDB advice needed (collections, documents)

I’ve only been using one collection per database since my former projects only require so. But now I need to add login and account feature to my app. Should i create a new collection so the documents don’t mix up? Is having a collection for each type of data schema okay?

For example, I want to create a chatting apps. So I create 4 collections:

  • To store login data
  • To store profile data (or should i put this inside the login data document?)
  • To store one-to-one chat
  • To store group information and chats

Is that okay? Is there any better approach? Any advice would be appreciated.

  • i don’t know how to google these information :confused:
