GraphQL Overview

1. The GraphQL schema is where your GraphQL types are defined.

2. GraphQL types are connected to each other using fields, and they form a graph.

3. The Query, Mutation and Subscription types are special, since they act as entry point to the graph.

4. The GraphQL schema acts as the data provider, and it offers a set of capabilities the consumer can use.

5. To get data from a GraphQL schema, you need to write a GraphQL operation (often referred to as query) that selects the data and fields you need.
