title: GraphQL where is data stored?
body: <p>Brand new to GraphQL. It's my understanding that it is a query language for APIs. Ok, I get that. </p>
  
  <p>Reading today, GraphQL can be used with a DB but it doesn't require one. The latter part of this is what I don't understand. </p>
  
  <p>Where is this data stored if no DB is in place? </p>
