Description: A mutation schema in GraphQL defines the types and fields available for performing mutation operations, which are those that allow modifying data on the server. Unlike queries, which are used to retrieve information, mutations are essential for creating, updating, or deleting records in a database. This schema is structured similarly to that of queries but focuses on actions that alter the state of data. Each mutation can have a return type, specifying what data will be returned after the operation, thus allowing the client to know the result of their action. Mutations are fundamental in applications that require interactivity, such as registration forms, profile updates, or item deletions. Clarity in the mutation schema is crucial for the efficient development of APIs, as it provides guidance on how to interact with data and ensures that operations are performed consistently and predictably.
