如果有的话，MVC 模式与 DAL/BLL 设计模式有何不同? [英] How does the MVC pattern differ, if at all, from the DAL / BLL design pattern?

问题描述

我正在学习早期的数据访问教程 在 Microsoft 的 ASP.NET 网站上，我突然想到这一切似乎与我读到的有关使用 MVC 模式.作为一个新手，我还没有实现 MVC 模式，但我很好奇这两种设计结构有何不同，以及我是否应该将注意力集中在一个或另一个上，尤其是在网页设计的上下文中.

I'm making my way through the early Data Access Tutorials on Microsoft's ASP.NET website and it occurred to me that this all seems awfully similar to what I have read about separating your logic and presentation code using the MVC pattern. As a newbie I have yet to implement the MVC pattern but I'm curious as to how these two design structures differ and if I should be focusing my attention on one or the other, particularly in the context of web design.

推荐答案

您为数据访问教程发布的链接是 MVC 模式的实现.MVC模式是一个概念，实现可以不同；你在 ASP.NET 中有这个，而在 Java 中有一个名为 Struts 的框架，它是一个实现 MVC.

The link you've posted for the Data Access Tutorial is implementation of MVC pattern. MVC pattern is a concept, implementation can differ; you have this in ASP.NET whereas in Java there's one framework called Struts, which is an implementation MVC.

DAL &BLL 模式在概念上与 MVC 模式不同；但不是这个特定的实现.MVC 实际上是通过使用 DAL、BLL & 来实现的.查看模式.

DAL & BLL patterns differ from the MVC pattern in terms of concepts; but NOT this specific implementation. MVC is actually achieved through usage of DAL, BLL & View Patterns.
