Examination arrangement management method in the MySQL table structure design of the online examination system

With the popularization and development of the Internet, the online examination system has become a widespread use in the current education field A teaching and examination tool used. The MySQL table structure design of the online examination system plays a vital role in the stable operation of the system and examination arrangement management. This article will introduce in detail the examination arrangement management method in the MySQL table structure design of the online examination system, and provide specific code examples.

1. Requirements Analysis

Before designing the MySQL table structure, we first conduct a requirements analysis to clarify the functional requirements of the system. The examination arrangement management of the online examination system mainly includes the following aspects:

1. Exam information management: including basic information such as examination name, examination subjects, examination time;
2. Exam score management: Including students' test scores, test rankings and other information;
3. Exam monitoring and management: including monitoring of the test process and anti-cheating treatment;
4. Exam question management: including addition, deletion, modification and checking of questions, etc. ;
5. Student information management: including basic information of students and examination registration and other operations.

2. MySQL table structure design

Based on the above demand analysis, we can design the following MySQL table structure:

1. Exam information table (exam_info) ：

##Field nameTypeDescription##exam_idexam_namesubject_idexam_time...

int(11)	Exam ID, primary key
varchar(100)	Examination name
int(11)	Subject ID, foreign key associated chart of accounts
datetime	Exam time
...	Other fields

Examination score table (exam_score):

Field namescore_idstudent_idexam_id score...

Type	Description
int(11)	Score ID, primary key
int(11)	Student ID, foreign key associated student table
int(11)	Exam ID, foreign key associated with the exam table
float	Test scores
...	Other fields

Examination monitoring table (exam_monitor):

Field namemonitor_idexam_idmonitor_status...

Type	Description
int(11)	Monitor ID, primary key
int(11)	Exam ID, foreign key associated with the exam table
int(1)	Monitoring status (0-normal, 1-cheating)
...	Other fields

Exam question list (exam_question):

##Field nameTypeDescription question_idint(11)Question ID, primary keyexam_idint(11)Exam ID, foreign key associated exam tablequestion_contentvarchar(500)Question content......Other fieldsStudent information table (student_info):

Field nameTypeDescriptionstudent_idint(11)Student ID, primary keystudent_name varchar(50)Student name......Other fields 3. Code example

Create exam information table

CREATE TABLE exam_info (
  exam_id INT(11) AUTO_INCREMENT PRIMARY KEY,
  exam_name VARCHAR(100),
  subject_id INT(11),
  exam_time DATETIME,
  ...
);

1. Create exam score table

CREATE TABLE exam_score (
  score_id INT(11) AUTO_INCREMENT PRIMARY KEY,
  student_id INT(11),
  exam_id INT(11),
  score FLOAT,
  ...
);

2. Create exam monitoring table

CREATE TABLE exam_monitor (
  monitor_id INT(11) AUTO_INCREMENT PRIMARY KEY,
  exam_id INT(11),
  monitor_status INT(1),
  ...
);

3. Create exam question table

CREATE TABLE exam_question (
  question_id INT(11) AUTO_INCREMENT PRIMARY KEY,
  exam_id INT(11),
  question_content VARCHAR(500),
  ...
);

4. Create student information table

CREATE TABLE student_info (
  student_id INT(11) AUTO_INCREMENT PRIMARY KEY,
  student_name VARCHAR(50),
  ...
);

5. The above is a specific code example of the examination arrangement management method in the MySQL table structure design of the online examination system. In actual development, function implementation and logic processing also need to be carried out according to specific business requirements. I hope this article can help you design and develop the database table structure of the online examination system.
