什么是3层编程 [英] what is a 3 layer programing

问题描述

我霍尔，

我是Code项目的新手，我现在正努力提高我的编程技巧。我正在使用C＃.Net，我想了解更多关于3层编程的信息。



谢谢

解决方案

与4层相同，不使用其中一个层。 :-)



更严重的是，看看我对这个问题的评论以及这里：

http://en.wikipedia.org/wiki/Multilayered_architecture [ ^ ]，

http：/ /en.wikipedia.org/wiki/Multi-tier_architecture [ ^ ]。



不多，对吧？这是因为这些概念过于笼统。尽管使用3是一种非常流行的做法，但没有一位认真的作者会坚持认为这三者在基本和普遍的重要性。硬编码立即常数是坏的，为什么硬切削架构应该是好的？

I Hall,
I am new in Code project, I am now trying to emprove my skills on programing. I am using C#.Net and I would like to understand a little bit more about 3layer programing.

Thank you
Bhunny

解决方案

Same as 4 layer, only one of those layers is not used. :-)

More seriously, look at my comment to the question and also here:
http://en.wikipedia.org/wiki/Multilayered_architecture[^],
http://en.wikipedia.org/wiki/Multi-tier_architecture[^].

Not much, right? This is because the notions are way too general. And even though using 3 is a very popular practice, no serious author will insist on those 3 as fundamentally and universally important. Hard-coding immediate constants is bad, why hard-cut architectures should be good?
