title: Name Firestore and Realtime Database fields
body: <p>I have seen a lot of people using &quot;accountName&quot; but some people are using &quot;account_name&quot;, Currently I think it makes more sense with &quot;account_name&quot; because it's not a variable it's just a field and it's more clear when I read a ton of string.</p>
  <p>Is there any standard or specification for the NoSQL database fields name? If not which one do you prefer?</p>
