Next, rebuild the charging system for data centers (I) Ii. Outline Design The use case diagram is completed, and the requirement analysis specification is improved in combination with the use case diagram. The number of revisions to the requirement analysis specification is missing. With the use case diagram, it is natural to enter the outline design stage. I think this phase is to solve the basic architecture of the system with the package diagram.

The Charging System of the IDC room has started for a while, but I feel that I still don't have a deep understanding of this line, which makes it difficult to log on later. So I will analyze the user login process. If it is a pure Layer 3, it is similar to understanding, it is nothing more than transfer between the layer and layer, but with the user demand, more and more software functions, then the complexity is growing. Therefore, we have introduce

I learned about the view in database learning and self-examination a year ago. At that time, I only learned the theory. This time I personally practiced it in the reconstruction of the data room charging system, which deepened my understanding of the view. Definition: From the outside of the database system, the view allows you to view data in the database from a specific perspective. Within the database system, the view is a virtual table defined

I wrote a view and a trigger on my blog two days ago. I didn't want to write a stored procedure. I just wanted to use it. however, I encountered a lot of problems in the process of using them. If I don't make a conclusion, I will still use them incorrectly. Why should I use it in the IDC charging system? Before that, my answer is: because everyone is using it, it will definitely be used. Now, my answer is: Because it can write and store frequently-us

Label: style blog HTTP color Io ar use for strongZookeeper The so-called expert is the person who has made all the mistakes in a very small field. --------- Question The data center charging system has been in place for some time. Now, students are offline. When a student disconnects from the machine, the corresponding checkout service needs to be performed based on different user categories. As a result, he has come up with the design model he has l

Disclaimer: the following content only applies to queries on-board records (combined queries) of students, and queries on-board records only for operator work records (combined queries! It is a bug. In fact, this is not a bug. It is just an error that is easy to make. If you don't pay attention to it, you can't find it. The following is a detailed description: There are three combined queries in the data room charging system: basic student informat

Test Plan (GB8567--88) 1Introduction Testing is required when the project's basic code is completed, which plays an important role in troubleshooting and fixing vulnerabilities. 1.1Purpose The main purpose of the test is to find as many vulnerabilities as possible in the system, design test cases, and test the system. The purpose is to have a general control over the testing methods and procedures. This document is intended for testers. System Testing accounts for 40% to of the total project de

procedure in one stored procedure. You can only call another stored procedure. Now that we know about the basic stored procedure, we use the creation and use of the stored procedure in the charging system of the data center. Here is an example.Iii. Example-refund of the IDC Charging System 1. First, create a stored procedure: Find the programmability in the database you have created-right-click the stored

Charging iPad on Windows is simple and I will not introduce it anymore, but it will take a little effort to charge it on Linux. Fortunately Google can find information, this iPadiPad2ChargeonUbuntu has been mentioned, how to charge the iPad on Ubuntu method: InstallationforiPadsudoapt-getinstalllibusb-1.0- Charging iPad on Windows is simple and I will not introduce it anymore, but it will take a little effo

1 IntroductionThe RAID card battery on the server, referred to as the BBU, is a very important component, it has a large impact on the I/O performance of the disk, but the general Bbu power can only be used for 90 days, the system will automatically charge it after the power is exhausted, but it usually takes a few hours to charge, during charging, The cache status of the RAID card is in write through, i.e. without the caching feature. So in order to

It took a total of five days from October 1 to October 2 to write the documents of the "Data Center billing system" for the first time. I used my knowledge in software engineering to practice it. The theory of software engineering is very boring, but it plays a very important role in guiding the production process of the system. This time, I spent nearly a week writing the "Data Center Charging System" document, and I have a new understanding of "dat

One of the most concerned questions about a new cell phone is how long it takes to recharge the phone for the first time. Some people used to say that the new mobile phone three times before charging to fill 12 hours, is actually not needed now, the phone is now used lithium, there is no so-called battery memory, so also do not have to fill 12 hours, We only need to charge when the battery is out of power, full of OK, and when it will be convenient to

This stage of the MVP website design has been initially embryonic, as follows:The functions of this system are as follows:Front Desk: Provide user registration and login functions, users can freely browse the site, login users can generate orders, and wait for the management to handle.Backstage: To implement the management website charging matters, processing orders, managing users and so on.Document completion is synchronized with the project, and de

Finally survived the winter, looking forward to the warm March ~ The weather gradually warm, the enthusiasm of the small partners to learn to rub against the rising up!Catch the wave of learning, hot hot "universal Charging Festival" also began ~ poke me to the event venue >>>At the same time, our "51CTO College" app also quietly happened to some changes yo ~ The careful classmate found it? The daily ritual becomes more beautiful, the gift is al

from the external to the built-in loss. Editor's summary: From this engineer's answer we see that he advocates that the new laptop does not have to activate the battery for a long time, and that in order to prolong the life of the laptop battery, it is best to drain the battery and recharge it every time; Finally we interviewed the friend is a "monastic years" of the book players, in the notebook technology has a lot of unique insights to see how he answered these questions: Q: Do we need to

Charging System in VB. NET data centerDuring personal refactoring, I found that the mshflexgrid control in VB6.0 was used in? Therefore, the datagridview control is displayed. But how can this control be used? Let's take the "query of collected amount" in the data room charging system as an example to explain how to use the datagridview control. The following figure shows the page for querying the cha

In fact, this data room charging system has been in conflict before it started, first of all, UML drawing feels that it was not learned well at the beginning, VB. net is over in just a few days. The design model should be converted to VB by using C # linguistics instead of learning well. net I feel that it is difficult, not to mention his examples are relatively simple when learning the design model, if used in engineering, it is hard to imagine. How

The charging system for data centers is nearing the end. With the improvement of system services and the improvement of functional requirements for various processes, code requirements become increasingly demanding, many times, to implement a function, you need to operate many tables in the database. These operations should be performed only when this function is implemented. Therefore, if we simply implement functions without considering the causal r

The data room charging system has the report function, which is a bit unfamiliar to us. Isn't it an accounting task? How is the data room Charging System Integrated? In fact, we have learned the report steps. After understanding the Code, it is not very difficult to report the report. Is it easy to climb the report! The following are the report steps. 1. Install the grid ++ report designer (download and ins
