 Every data model is defined as part of a data schema (`a.schema()`). You can enhance your data model with various fields, customize their identifiers, apply authorization rules, or model relationships. Every data model (`a.model()`) automatically provides create, read, update, and delete API operations as well as real-time subscription events. Below is a quick tour of the many functionalities you can add to your data model:
 
 ```ts
-import { a } from "@aws-amplify/backend";
