data center diagram visio

I recently worked on a. net data center charging system, which is compared with a simple three-tier system. Now I will post it to share with you! Package diagram: The design mode (Abstract Factory) is applied, so that there is no need to have a relationship (application interface) between layer B and layer D, and the abstract factory + reflection + configuration

goes, a picture can express the emotions and world that cannot be depicted in words. Now let's take a look at the package diagram of the data center charging system, as shown below: First, let's analyze what we need to do to log on to the system, determine whether the user exists, and determine whether the user name and password are consistent. After the login i

attention to details and contact demands I didn't pay attention to comments when I first started drawing the image. As a result, I picked up the image for a while and couldn't even understand it myself, let alone others. The other aspect is that there is a huge difference in comments between the document and the code. Annotations should be fully written and should be detailed as much as possible, including every class, every method, and every variable. This is because you are familiar with t

Restructuring of the vb.net data center charging system-Summary (1) combing the business and table structure, vb.net Charging System The Charging System of the IDC room has been in progress for some time. I have received a notification two days ago and want to spot check the IDC for reconstruction. I have also become one of them. Therefore, although the IDC room has been accepted, we have re-checked, debugg

Data Center reconstruction-why do we need to separate the card table from the student table? During the reconstruction of the fee-based database in the IDC room, the previous Studetn_Info was divided into Card_Info and Student_Info. It is easy to know that it is used to decouple the students and cards, however, how to design the form and code can be used to embody the idea. I did not have my own opinions un

HTML5 big data visualization effect (1) rainbow explosion diagram, html5 Visualization Preface 25 years later, Dr. Brooks's famous "no silver bullet" statement was still not broken. The same is true for HTML5. But this does not prevent HTML5 from being an increasingly powerful "blow-up": rapid development and unstoppable. With the popularization of HTML5 technology, more and more projects are presented vis

plotted on the y-axis. An axis perpendicular to the intersection of two points with a marker on the chart. When a large number of these pairs are drawn, a graph appears. The important function of scatter chart is that it can be used to draw the function curve, from simple trigonometric function, exponential function, logarithmic function to more complex mixed function, can use it to draw the curve quickly and accurately, so it is often used in teaching and scientific calculation.5 Bubble chartA

interested, you can try it. The test results of the other options are different.The other, for the first time, selected a 1-minute chart for testing, and found that the test results were very poor. Then we selected some of them for testing separately. Finally found that 15 minutes-1 hours of graphics accuracy is high, for the long-term, the historical test and actual test results are basically similar. You can also try it with your own ea. Personal feeling chart period is large, there will be n

Introduced The waterfall diagram is a useful tool for drawing certain types of data. It is not surprising that we can use pandas and matplotlib to create a repeatable waterfall diagram. Before I go down, I want to tell you what kind of chart I'm referring to. I will build a 2D waterfall diagram described in wikipedia
