[Data room Charging System] how painful it is to understand

The IDC charging system is the least satisfactory among all projects.

Long time, slow efficiency. At the beginning, I felt like I could not start, but I always believed that I could enter the status slowly. Finally, I had the opportunity to practice my own hands. I thought that I had learned a good design model before, and finally I had the opportunity to think about the design model myself. This is a handsome thing. After dragging on for so long, now I have only used the appearance Abstract Factory template Personal Edition. I really don't want to take another day.

In other words, I do not think that I think it will be much worse than others when coding. At the beginning, I knocked on three layers and began to draw pictures. Still confused. After designing the database, I finally had my own thoughts and relived the database principles I learned before. The painting phase is quite rough. To tell the truth, although I knocked three layers twice at the time, I began to draw examples of graph or something, which is still relatively abstract. Later, I began to knock on the data center, paving the way for various problems.

 

Online query?

When talking about the layer-7 design pattern at the beginning, I thought about it myself. Big talk design model. I don't have a clue for a few days, so I really don't want to read it again. Later, I asked others, saying that this kind of things is a big basket on the Internet.

Are these things really going to be checked online?

This is my first thought. Why are you not standing on the shoulders of giants. If you don't know something, you just need to check it and ask. Don't think about anything on your own. This is wrong. Something like sqlhelper cannot be abstracted at the beginning. If you don't know how to do some things, you just need to check it and try it out. I will not. I will check more, and I will practice it. Then I will go back and reflect on the shortcomings and where to modify them. How nice it is.

 

Term?

I didn't give myself a definite deadline. This problem cannot be solved. Deadline for yourself. However, I spent the same time as most people. The foundation is not very poor. It's not that bad. I also feel more steadfast in my previous studies .. I am sad ..

 

I think I have not transformed my learning methods and learning ideas at this stage? As a result, I used my previous ideas to impede my current learning.

 

The above is basically all of your own expressions. I have exposed my problems. I hope some of you can give me some advice.

 

Next, let's talk about our achievements in the data center charging system.

Draw a picture first and then code it. In particular, class diagrams are drawn. I feel very helpful to myself. In the future, I think about that image.

Newly learned stored procedures and things also use views and joint queries. It can be used to build a physical set. You can also clearly understand a line by yourself. What's more, we have a clearer understanding of layering. Mr. Mi said that he would have to go through this stage just like learning a bicycle by himself.

 

Alas ~~ Painful comprehension... Wait for me for the next project...
