    Modeling a GraphQL API
    data
    modelling
    1. Using “endpoint style” rather than
    thinking in graphs
    2. Mapping their GraphQL schema
    directly to their database tables
    (foreign keys and all)
    3. Mapping their GraphQL schema
    directly to their back-end data model
    (eg. your model classes from your
    ORM or the like)
