Billing System for IDC Rooms-reflection + Summary

 

There was no excitement when the data room charging system was knocked out, because it took three months for others to knock on the system for a few days. This is a summary blog and a reflection blog.

This data room charging system found that I had a lot of problems, and I had to choose to escape from the difficulties and indulge in the pressure. I am so nice to myself, so I always find reasons to forgive myself! In fact, after you finish looking back, you can scare yourself, and all of them are paper tigers. It is not difficult for the data center charging system to overcome itself. Three months, 90 days, it will always accompany me, spur me!

Next, let's talk about some of the problems we face when working on the data center. The first is to analyze the requirements. This process is very important. When I first started, I always felt confused and did not know how to start it. Then I dragged on and delayed a lot of time, and made my own psychology highly resistant to the data center charging system, as a matter of fact, I quietly analyzed it and found that there was nothing to do. Just draw it according to its business process, mainly to overcome my fear and be brave enough to do it.

Then there is a concrete implementation without psychological barriers. It is much easier to do, mainly through combined query, checkout, and report. These three major knowledge points train your logical thinking. There is also the code specification, which is a habit that our programmers must abide by and develop. Remember that we do not write code for ourselves. Another point is that you can't just do it. Sometimes the more you think about it, the more chaotic you are, the less you don't know how to do it. Only by timely hands-on practices can we better clarify our ideas and discover problems.

Finally, it is acceptance. In this process, the master gave a lot of suggestions and questions. Check whether basic functions, logical understanding, and code are implemented correctly. The most important thing is whether to consider the problem from the user's perspective and whether it serves the people. The problem is summarized, debugged, and summarized.

This process is really difficult. Fortunately, it has been stuck for three months and ninety days. It will always accompany me and spur me!
