And putting entities' behavior in services or the view layer scatters the entities' core logic throughout the application, causing maintenance problems.

另外，把实体的行为放在服务或视图层中，会导致实体的核心逻辑分散在应用程序中的许多地方，导致维护问题。

The client (browser) just acts as a view, while the application runs on the server and has complete access to resources like databases, Web services, and so on.

客户机（浏览器）只充当一个视图，而应用程序在服务器上运行，并且能够完全访问数据库、Web 服务等资源。

Typical Web services employ a remote presentation paradigm, meaning all view logic executes on the client, whereas the application logic and the data layer (controller and model) reside on the server.

典型的Web服务使用远程表示范例，这意味着所有的视图逻辑在客户机上执行，而应用程序逻辑和数据层(控制器和模型)则驻留于服务器上。
