Data room charging system VB (1)-system analysis, charging system vb
First, let's answer two questions:
1. What is the charging system for the IDC room "?
2. What should I do with the data room charging system "?
My answer:
1. As the name suggests, the data center charging system is a charging system.
2. The main task flow of the data room charging system is registration-recharge-go-machine-go-back. Other functions are the main responsibilities of various personnel.
Then, let's further analyze the functions of this system.
We can compare this system to a charging system for Internet cafes, and it mainly targets students. Even if a student is on the computer, we must also have personnel on duty and administrators. General Users:
StudentOPERATOR:
Personnel on dutyAdministrator:
Network ManagementWhat are their respective functions? Let's take a look at a picture to see what they are responsible!
Seeing such a classification, this system is nothing more
Add, delete, modify, and query a setAlthough the content is different from that of the students, the basic structure is similar. When the master says that the computer room is used, he must use the things mentioned in the video, so we make persistent efforts! Serve the people wholeheartedly! Here I made some modifications to the original system.
The student's computer status is queried by the personnel on duty, because the student has no permission to deprecate all the students or selected students.. Here we talk about permissions. We simply analyze the permissions of this system.
The minimum permissions are granted to students. The personnel on duty have intermediate permissions, while the network administrator has advanced permissions.That is to say, (1) students can only perform operations on the functions under the general user menu, but cannot perform operations on the functions under the operator and administrator menu. When the login user is a student, only the general user menu can be used, operator and administrator menu is not available; (2) on-duty personnel can operate not only the functions under the operator menu, you can also perform operations on the functions under the general user menu. When the logged-on user is an operator, the user and operator menu can be used, but the Administrator menu cannot be used. (3) the network administrator can operate on all functions! When the logged-on user is the administrator, the user, operator, and administrator menus can be used.
Finally, the simple analysis of the system is here. I have been studying the system for the past two days. I have observed and analyzed the system and summarized it. The understanding of some things may not be so deep. In the following process, modify it at the same time!
How does access and VB combine to design the charging system of the data center?
Let's see what you want.
