Hi All,
I have been studying C# recently and covered all the basics. At this stage of my learning journey I am struggling with the concepts of application architecture. The various layers and what happens at which layer.
答
对于ASP.net您可以创建以下图层
1）DAL层：用于数据库。所有与DB相关的操作只应在此处执行，否则应该访问DB。
2）BusinessLayer：您可以在哪里定义业务逻辑。
3）表示层：用户的UI显示。

For the ASP.net You can create following layers
1) DAL Layer: Which is used for the database. All the DB related actions should be performed here only, no where else DB should accessed.
2) BusinessLayer : where you can define the business logic.
3) Presentation Layer: UI display for the user.
