问题描述
我接受了采访，为此我需要学习一些概念.
我在3层架构中进行了大量搜索，并从下面的链接中了解了这一概念，
1.lokeshchadha.blogspot.in/2012/06/3-tier-architecture-example-in-aspnet.html
2.www.dotnetfunda.com/articles/article71.aspx.
现在我的疑问是，
1.在第一种方法中(第一个链接)
我不明白该如何传递在BL中定义的参数.
2.第二种方法(第二个链接)
BL中没有分离的逻辑，这里只需调用DL方法，
并在PL中再次创建BL的obj并调用BL方法，这里BL的用途是什么.
我对这个概念是陌生的，这就是为什么我有这些疑问.
任何人都可以澄清我的疑问或给我一个简单的示例，清楚地说明有关3层体系结构的问题.
Hi,
I have an interview ,for this I need to learn some concepts.
I searched a lot for 3-Tier architecture.I read about this concept from the below links,
1.lokeshchadha.blogspot.in/2012/06/3-tier-architecture-example-in-aspnet.html
2.www.dotnetfunda.com/articles/article71.aspx.
now my doubts are,
1.In first method(first link)
I am not understand how was the parameters are passed those are defined in BL.
2.In second method(second link)
there is no separete logic in the BL,here just call the DL methods,
and in PL again created obj of BL and call the BL methods,here what is the use of BL.
I am new to this concept that''s why I got these doubts.
Can anybody clarify my doubts or give me simple example that clearly explains about 3-Tier architecture.
