The final version of--UML diagram of computer room reconstruction

At the beginning of the painting is really tangled, at that time was forced to draw under the master, but it is also good, in the strong request of master, I learned how to use the EA, but also for a learning a new software has a better way to find some video, or text materials to help us learn to use the new software.

Each time the drawing has a new understanding, after this and the regulation of the consolidation of software requirements have a deeper understanding, we have so many layers is to be able to better decouple.

Here is my picture of this personal refactoring

U-Layer: Each function is a class

Facade Layer:

Further improvement: it is difficult to understand how each function should be divided into which class it should be, so that it can be balanced and the timing diagram is not particularly complex.

B-Layer

Entity layer:

Layer D:

Summarize:

This is my final design of the diagram, although more than the first time there is a great change, but there are some problems, the biggest problem is that the functional classification is not clear enough, resulting in a number of events in individual classes, easy to cause confusion. This is also their own a process of groping, I believe in the computer room cooperation is able to have a better improvement. At the same time, we must also thank the imperfect, imperfect means that we can grow, we are in the improvement of the growth. The personal reconfiguration of the machine room has been completed, but each completion does not represent an end and heralds a new beginning.
