When you implement a GraphQL server, you don't map GraphQL to SQL. Instead, for each object type in your API, you define how to resolve each field, and you can use one of the various GraphQL server libraries to go from those object types to serving a whole API. I would get more specific but it depends on which programming language you want to use. Check out the code examples & links to libraries in different languages on http://graphql.org/code/ http://graphql.org/code/
