Analysis of IDC Charging System Requirements

The previous student management system is based on source code. Therefore, analysis is much easier. The data center charging system is different this time. It can be said that it is a test of our development journey.

Before developing the system, the first step is to analyze the requirements! Requirement Analysis is a key step in system development. That is, weDo you know what the data center charging system is? What is it?

The data room charging system is required to enable students to have an environment to practice on the computer and to manage these students with a pay-as-you-go approach. For example, before the computer grade examination we conducted in freshman year, if you want to practice the exam questions, go to the machine room.Who uses this system? There are three main types: general users, operators, and administrators.

What are the functions of the system? Each user has different functions. For example, if the average user or student level is the lowest, the user has less permissions, so he can only perform the following operations. The operator has high permissions, so it has many functions. The Administrator is the user with the highest permissions and can perform operations on the entire system. The functions of each user are as follows:

 

Generally, teachers on duty in the IDC are mainly responsible for helping students view their basic information.

 

Operators are mainly responsible for viewing student information, handling relevant procedures for students, and viewing records.

 

 

The administrator can manage the entire system. In addition to the functions of common users and operators, the Administrator also has several unique functions. One is to manage users, that is, to add and delete users; the second is billing management, which collects the check-out information and related reports.

 

Good management information systems are based on the database technology. The Charging System of the IDC is no different. Finally, 12 data tables are created through functional analysis. In the process of creating a data table, efforts should be made to standardize the data table to improve the structure, sharing, consistency and operability of the data. Therefore, in the subsequent process, we must constantly improve these data tables.

After analyzing the system functions and data tables, we will start charging the system for the data center.
