三层与 n 层之间的差异 [英] Difference between three tier vs. n-tier

问题描述

我刚刚看到以下句子:

随着行业从三层模型到 n 层模型，对象关系阻抗失配变得更加普遍.

As the industry has moved from a three tier model to n-tier models, the object relational impedance mismatch has become more prevalent.

但是我找不到关于三层和 n 层之间区别的简明解释.我知道三层是什么，我假设 n 层只是增加了一层或多层.我只是不确定这些额外的层是什么.如果有人有简短的解释或只是一个好的链接，那将不胜感激.

But I can't find a concise explanation of the difference between three tier and n-tier. I know what three tier is, and I assume n-tier just adds one or more tiers. I'm just not sure what these additional tiers would be. If anyone has a short explanation or simply a good link, that would be much appreciated.

推荐答案

引用似乎来自这个 codeproject 页面.它似乎也很好地解释了 n 层以包含 Web 服务、javascript、工作流等内容.3 层模型不一定包含所有内容.

The quote appears to be from this codeproject page. It also seems to do a pretty good job of explaining n-tier to include things like web services, javascript, workflows, etc. All things that 3-tier models don't necessarily include.

这篇关于三层与 n 层之间的差异的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
