title: How can I structure data in Firebase database?
body: <p>I need to develop an app for university, but I don't know how to structure my data in Firebase.</p>
  <p>In my app there are users who can create events with different questions.
  Example: an event poker tournament is created with 2 questions.
  1st question: Do you participate?,
  2nd question: Have you ever played poker?</p>
  <p>When the event is created, users can answer yes or no to each question. The organizer should be shown the number of yes and no answers per question.
  Furthermore, the users should be able to see all the answers they have given.</p>
  <p>I am new to Firebase and would need your help.</p>
  <p>I use the Firestore database and program in Kotlin</p>
  <p>Thanks</p>
