I am learning about GraphQL and Apollo , i can say that i got most of the concepts easily, i am learning it from the docs, but i am still stuck with some terms that overwhelmed me a little
In Apollo docs, they are saying:
A data graph sits between application clients and back-end services, facilitating the flow of data between them: An Apollo data graph uses GraphQL to define and enforce the structure of this data flow.
I can’t relate this to graph data structure 100%, so i am still confused:
1 - What is the exact meaning of a data graph sits between client and backend?
2- What is the exact meaning of data graph here?
