3 层架构和 mvc 有什么区别?

它们是一样的吗?

两者都有 3 层，即模型、视图和控制器

解决方案

与MVC架构对比

<块引用>

乍一看，这三层似乎与模型-视图-控制器 (MVC) 概念；然而，在拓扑上它们是不同的.三层架构的基本规则是客户层从不直接与数据层通信；在一个三层模型所有的通信都必须经过中间层.从概念上讲，三层架构是线性.然而[模型-视图-控制器] MVC 架构是三角形:视图发送更新控制器，控制器更新模型，然后视图直接从模型更新.

what is the difference between 3 tier architecture and a mvc ?

Are they same?

Both have 3 layers i.e model, views and controller

解决方案

Comparison with the MVC architecture

At first glance, the three tiers may seem similar to the model-view-controller (MVC) concept; however, topologically they are different. A fundamental rule in a three tier architecture is the client tier never communicates directly with the data tier; in a three-tier model all communication must pass through the middle tier. Conceptually the three-tier architecture is linear. However, the [model-view-controller] MVC architecture is triangular: the view sends updates to the controller, the controller updates the model, and the view gets updated directly from the model.
