Data Center reconstruction (Personal Edition)-class diagram

I think the correct sequence of Data Center reconstruction is: database, drawing (package diagram, class diagram, timing diagram), and the implementation of code at the end of the document. However, although I think so, I did not fully follow this process. In my opinion, the Plan and sequence are dead, and people are living. What if you do not go down after a certain step?

My choice is to put it down and start with other methods. For the second IDC, I first made a package diagram and made a simple class diagram (there is a feeling that I don't know where to start or how to start ), it is not much different from the first class graph, because I have not found the starting point. I made several Sequence Diagrams (basically all of them were wrong and all of them were changed ). On the basis of these half-failure figures, I started a long journey of code. I want to use the code to improve my graph, especially the class graph.

So much of the above is that, before I start to use the three-tier idea to make several forms, it is a little difficult for me to draw pictures. Therefore, I first made several forms and became familiar with the hierarchical logic. At this time, I felt a lot better.

For the class diagram of the first data center, the class diagram model was mainly classified by personnel. below is my first class diagram. You are welcome to correct it.


Put it here, mainly to say that learning is a step-by-step process. Although there are many errors in the middle, the growth of the view is always a great encouragement. This class chart is detailed from the perspective of layering, and the class granularity is also very small. Of course, there may be some errors. I hope readers can point out that everyone will make progress together, after all, I have just finished this class chart.

The first is the class graph at the U layer, which starts from each form and writes the method of each class.


The class diagram of layer B writes out the class and return value of layer B.


The class graph of layer D writes the method, attribute, and return value of the class of layer D.


Finally, the class diagram of the appearance Layer


Put the figure into a blog here. It is mainly intended for readers to point out errors. Secondly, it also provides readers with a way of thinking. They can also discuss and share with each other and make progress faster!
