3.4 Database design

3.4.1 Database conceptual design

Database design must follow several rules. First, logical thinking needs to be organized before database design. This process is usually implemented with the help of E-R diagrams [14]. Secondly, when designing tables, pay attention to whether the field formats in the tables are correct, otherwise data errors will occur. , in addition, we must also follow the rules of the paradigm and try to avoid errors in the database.

3.4.2 Database E-R diagram design

The E-R diagram is a step that database designers should take before implementation. It embodies logical thinking and displays the management between database tables in a visible form. The E-R diagram can help designers observe the database and improve the feasibility of database implementation. .

3.4.3 Database design

The following is a partial data table display of the development and design of the university student management system:

The student table stores student user information registered on the home page of the art troupe, including fields such as student name, account password, personal avatar, personality preference (as review information for entering the art troupe), as shown in Table 3-1.

Table 3-1 xuesheng student table

Field Name	type	length	Field description	primary key	default value
id	bigint		primary key	primary key
addtime	timestamp		creation time		CURRENT_TIMESTAMP
xingming	varchar	200	Name
mima	varchar	200	password
xingbie	varchar	200	gender
touxiang	longtext	4294967295	avatar
shouji	varchar	200	cell phone
zhuanye	varchar	200	major
xingquaihao	varchar	200	hobby
gerentezhang	varchar	200	Personal strengths
ziwopingjia	varchar	200	Self-evaluation

The leader table records the relevant identity information of the leader of the art troupe, including the name of the leader's art troupe, the leader's personal account password, personal information, avatar, audit information and other fields. After the leader's identity is registered in the backend, it needs to be confirmed by the administrator. Review. If the review fails, the team leader's identity will be locked and he will not be able to log in. Only after the review passes, the team leader can log in to the backend management system page, as shown in Table 3-2.

Table 3-2 Tuanzhang leader list

Field Name	type	length	Field description	primary key	default value
id	bigint		primary key	primary key
addtime	timestamp		creation time		CURRENT_TIMESTAMP
yishutuanmingcheng	varchar	200	Art troupe name
mima	varchar	200	password
tuanzhangxingming	varchar	200	Team leader name
xingbie	varchar	200	gender
touxiang	longtext	4294967295	avatar
lianxidianhua	varchar	200	contact number
sfsh	varchar	200	Whether to review		Pending review
shhf	longtext	4294967295	moderation reply

The user table is used to record the identity of the administrator and mark the administrator's personal information, as shown in Table 3-3.

Table 3-3 users table

Field Name	type	length	Field description	primary key	default value
id	bigint		primary key	primary key
username	varchar	100	username

Continued from Table 3-3 users table

Field Name	type	length	Field description	primary key	default value
password	varchar	100	password
role	varchar	100	Role		administrator
addtime	timestamp		Add time		CURRENT_TIMESTAMP

Art group information table. After the group leader's identity is approved by the administrator, the group leader can log in to the back-end management system to create his own art group, including the name, announcements and other information related to the art group, as well as the avatar of the art group, etc., as shown in Figure 3-4 shown.

Table 3-4 yishutuanxinxi Art Troupe information table

Field Name	type	length	Field description	primary key	default value
id	bigint		primary key	primary key
addtime	timestamp		creation time		CURRENT_TIMESTAMP
yishutuanmingcheng	varchar	200	Art troupe name
yishutuantupian	longtext	4294967295	Art troupe pictures
yishutuanleibie	varchar	200	Art Troupe Category
yishutuanzongzhi	varchar	200	Mission of the art troupe
yishutangongggao	longtext	4294967295	Art Troupe Announcement
chuangbanriqi	date		Founding date
lianxidianhua	varchar	200	contact number
xinxijieshao	longtext	4294967295	Information introduction
crossusers	bigint		Cross-table user id
crossrefid	bigint		Cross-table primary key id
sfsh	varchar	200	Whether to review		Pending review

5.1 Login and registration function

5.1.1 Student registration and login

Student registration requires filling in personal name, password and basic personal information. This information is convenient for the group leader to quickly review when entering the art troupe. (See Figure 5-1 for details).

Students log in and check whether the account number and password are correct. After the password is correct, students can use functions such as registration activities and group application on the homepage. (See Figure 5-2 for details).

5.1.2 Backend identity login

Three background identities: administrator, team leader, and student can log in on this page and enter the management system. (See Figure 5-3 for details).

6 system test

6.1 Test purpose

Art troupe management has undergone space changes with the development of the Internet. Modern art troupe management is more about quality. Whether it can complete management needs and the convenience and completeness of management needs are the goals that need to be pursued. Therefore, in order to make the system mature and effective, the quality of the system itself must pass the test and must be checked. Therefore, after we complete the system construction, we still need to strictly test the system to ensure that there will be no errors and loopholes in the system operation, so that the system can be promoted more effectively. This is an important link in the development process, and the test results directly affect the quality of the system.

6.2 Test content

We mainly conduct black box testing on the system. Through black box testing, we can discover possible risk issues in the system and ensure the smooth operation of the system. Black box testing can accurately feedback user data and quickly execute relative functions to ensure complete input and output of functions.

6.3 Test cases and results

The design of the art troupe management system basically achieved the ideal effect, performed well in all aspects, and basically met the daily needs of each user. Through this test, we focused on checking the stability of the art troupe in the operation of the three roles to ensure that System errors will not occur during actual use, and errors can be automatically checked during system operation. The test results are shown in Table 6-1.

3	Group leader registration function	1. Register the group leader in the background and fill in the corresponding information 2. Failed after logging in 3. After the administrator passes the review, the login will be displayed as successful.	Test success The team leader can log in and the administrator can conduct audits.	pass
4	Event application management	1. The group leader adds event information to the page and clicks Submit. 2. The administrator chooses to pass the group leader activity review on the interactive registration management page.	Test success The event appears on the homepage and you can register to participate in the event	pass
5	Fund application management	1. The team leader fills in the relevant information and applies for funds on the funding application page. 2. On the administrator’s funding page, you can see the information to be reviewed and choose whether to pass it.	Test success The team leader can check that his funding application has been approved	pass
6	Contribution points management	On the art troupe member management page, the leader clicks Add Contribution and fills in the relevant information to give extra points to the art troupe members.	Test success Students can check their current points status on their contribution management page.	pass

Through test cases, the functions of login and registration, event registration, fund management, and points contribution management of the art troupe management system are monitored, which provides technical support for the later practical application of the system. Administrators can manage all art groups to the maximum extent and have absolute control over the layout of the home page. The leader can manage the members of the art troupe, and students can participate in art troupe activities.
