Here the different models of the database:

One important thing to have in mind that is different from sql in mongo is:

In general, you should structure your schema so your application receives all of its required information in a single read operation.

Note

• type: [’note’, ’todo’, ‘private’,….] - Different type of notes, for not we are only considering note
• visibility: [‘public’, ‘private’] - Note public or private
• content: The content of the note
• _id: Id of the note with the format YYYYMMDDHHMMSS
• out_relations:
  • _id
  • title
  • type
  • visibilty
• in_relations:
  • _id
  • title
  • type
  • visibilty
