the three-tier architecture:
1. Easy Project Modification and maintenance. During project development or after development, or even during project migration. This three-tier architecture is very convenient. For example, to migrate a project from Web to Form, we only need to repeat the presentation layer. The remaining two layers do not need to be changed. You only need to add them to the existing project. If this architecture is not used, the code is
There are too many design patterns in the garden. Recently I have also learned the design patterns and sorted out some codes I have practiced and wrote them. net Design Pattern learning notes to give yourself a deeper understanding of the design pattern.

First of all, I want to declare that I am not very familiar with ibatis, and I am still in the learning stage. I am only recording the process of learning ibatis. Of course, by following this process, you will eventually complete your first ibatis program. There must be a lot of unsatisfactory things, or something that needs optimization. I hope you can discuss this with me.
Why should I learn ibatis? It is actually very simple, because I can use 20% of the Code to complete 80% of the functions.

However, there are two problems in actual use. First, the computers on the DMZ bastion host are the same as those on the Internet and are exposed to external intrusion and virus attacks; on the other hand, DMZ host settings need to be separately divided into network segments.
