本文介绍了MVC（Model-View-Controller）设计模式的核心概念。模型（Model）负责存储数据并处理业务逻辑；视图（View）展示数据给用户并获取用户的输入；控制器（Controller）接收用户请求，并调用相应的模型和视图来更新状态和显示结果。
A controller can send commands to the model to update the model’s state (e.g., editing a document). It can also send commands to its associated view to change the view’s presentation of the model (e.g., by scrolling through a document).
A model stores data that is retrieved to the controller and displayed in the view. Whenever there is a change to the data it is updated by the controller.
A view requests information from the controller. The controller fetches it from the model and passes it to the view that the view uses to generate an output representation to the user.
