GraphQL Schema

A GraphQL schema is a blueprint that defines the structure of a data system, specifying the types of data available and how they relate. It acts like a detailed map, outlining exactly what information can be requested and in what format. This allows developers to query only the data they need, making data retrieval efficient and flexible. Think of it as a contract between a client and a server, ensuring clear communication about what data is accessible and how it can be obtained.
