My Design Patterns

This days, I am learnning the [Enterprise Soulation Patterns Using Microsoft .NET version 2.0], thorugh the learning, therefore a little content I readed, but I find that the design patterns is so important. Some patterns I used but I do not know, and my manager and a colleague talk about the three tier, I am dout that, even never heard that. When I find it in the ESP.NET, i am so please, and that is so easy(in my mind,my be because i have not researsh it deeply). I had watched the MSDN Webcast about the design pattern by Li Jianzhong, which is so abstraction and diffcult to unserstand.

Read this book is a easy way to design pattern, It is easy to understand, practise, you will find many patterns in the .NET Framework, also you will used that in your codes.

OK, the above is my  viewpoint, please pardon my liberty
