In the example schema above, the `@model` directive is part of Amplify's [GraphQL transformer](/cli/graphql/data-modeling) functionality and the `@auth` directive determines what [authorization rules](/cli/graphql/authorization-rules/) to apply. 
 
 A type decorated with the `@model` directive will scaffold out the database table for the type (Restaurant table), the schema for CRUD (create, read, update, delete) and list operations, and the GraphQL resolvers needed to make everything work together.
