推荐答案

您需要一个数据库.网络存储仅用于临时用途.

You need a database. Web-storage is only for temporary things.

如果您有后端，则可以使用服务和 $http 来创建 CRUD 应用程序.

If you have a backend, you can use a service and $http to create a CRUD application.

您使用 Angular 将数据发送到执行持久化的后端.

You use Angular to send data to the backend which does the persistence.
