We also recorded videos.

On March 29, November 21, the charging system for the Cooperative Development of Data Centers ended on the 21st to 29th, and completed a very special and interesting task. I used to watch videos recorded by others. This time, I recorded my own videos with two partners,
We call it a video project, from writing a project plan, daily report, improving the lecture content, sorting out materials, recording, and finishing the last week, which is a summary of our study during this period, it can be regarded as contributing to others.
 
Learn software engineering, learn to write documents, draw a UML diagram, go to the design mode, three-tier architecture, and finally use what you have learned to reconstruct the personal version of the data center charging system, and then learn about SVN to develop the data center charging system, this process is short or not long. Lost, happy, painful, and excited. The popular saying goes: pain and happiness.
 
I recalled that I had been entangled in not writing documents. Up to now, I have written n versions of the documents of the charging system of the data center, so I will not draw UML diagrams, up to now, the version of the data center charging system has reached 8.0, which is not a small scale. I don't know about the hierarchy, MVC, and I am looking for information myself. The old man deliberately cultivated our ability to search for food, "wolf-like students" are made slowly.
 
He gave me his advice. We recorded the learning of this period as a typical video. It mainly focuses on the application of UML, design mode, and three-tier architecture in the data center charging system. I am responsible for the implementation of the three-tier architecture in the data center charging system. A total of nine sets are recorded, one set is 20 minutes. Whether it can be used in the future, it is still very happy to be able to save your own Labor achievements. Of course, I hope it will be helpful to later users, even if it is for your criticism.
 
This video recording is still quite fruitful. It not only summarizes what we have learned during this time period, but also provides us with a deeper understanding and a better verbal ability, in a special environment, such as the ability to respond and control globally.

some problems also occur, the most important thing is that the three of us did not coordinate well and there was a problem with the inconsistency of the UML diagram versions. "They did not conduct commands in a uniform way, but they did everything in government! "There is no strict and unified design, follow the design, and avoid it !", It is worth reflecting on. For teamwork and command listening, I think we still need to improve. This awareness must be emphasized.
after the first time, I believe that it will not be so uncomfortable to record videos later.
at last, O min, de Peng, And I recorded a "summary", which is a summary of the joy of the project,. You make me feel that it is good to have you fight together. Come on.
