问题描述

什么是3层架构与MVC的区别？

他们是一样的吗？

两者都有3层即模型，视图和控制器

解决方案

的MVC架构比较

  

乍一看，这三个层次看起来类似
  模型 - 视图 - 控制器（MVC）的概念;然而，拓扑它们是
  不同。 在三层体系结构的基本规则是
  客户层从不直接与数据层通信;在一个
  三层模式的所有通信必须经过中间层。
  从概念上讲三层架构的线性即可。然而，
  [模型 - 视图 - 控制器] MVC架构的三角：视图发送
  更新到控制器，所述控制器更新模型，和
  视图获取直接从模型进行更新。

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.
