MySQL table structure design guide for school management system

With the continuous development and progress of society, the school management system has become an important part of each school's management of academic affairs, student information, and teachers. A core tool for important data such as information. As a commonly used database management system, MySQL is widely used in various software systems.

Designing an efficient and stable MySQL table structure for the school management system is the key to ensuring the normal operation of the system and data security. The following will provide you with a specific MySQL table structure design guide, including the necessary tables, fields and relationships, as well as corresponding code examples.

  1. Student information table (students)
    This table is used to store students' personal information, including student number, name, gender, age, class and other fields.

CREATE TABLE students (
id INT(11) NOT NULL AUTO_INCREMENT,
student_id VARCHAR(20) NOT NULL,
name VARCHAR(50) NOT NULL,
gender ENUM('male', 'female') NOT NULL,
age INT(3) NOT NULL,
class_id INT(11) NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY unique_student_id (student_id),
FOREIGN KEY (class_id) REFERENCES classes (id)
);

  1. Teacher information table (teachers)
    This table is used to store teachers’ personal information , including fields such as job number, name, gender, age, etc.

CREATE TABLE teachers (
id INT(11) NOT NULL AUTO_INCREMENT,
teacher_id VARCHAR(20) NOT NULL,
name VARCHAR(50) NOT NULL,
gender ENUM('male', 'female') NOT NULL,
age INT(3) NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY unique_teacher_id (teacher_id)
);

  1. Class information table (classes)
    This table is used to store class information, including class number, grade, major and other fields.

CREATE TABLE classes (
id INT(11) NOT NULL AUTO_INCREMENT,
class_id VARCHAR(20) NOT NULL,
grade VARCHAR(10) NOT NULL,
major VARCHAR(50) NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY unique_class_id (class_id)
);

  1. Course information table (courses)
    this The table is used to store course information, including fields such as course number, course name, and teacher.

CREATE TABLE courses (
id INT(11) NOT NULL AUTO_INCREMENT,
course_id VARCHAR(20) NOT NULL,
name VARCHAR(100) NOT NULL,
teacher_id INT(11) NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY unique_course_id (course_id),
FOREIGN KEY (teacher_id) REFERENCES teachers (id)
);

  1. Course Selection Record Table (course_selections)
    This table is used to store student course selection information, including student number, course number and other fields.

CREATE TABLE course_selections (
id INT(11) NOT NULL AUTO_INCREMENT,
student_id VARCHAR(20) NOT NULL,
course_id VARCHAR(20) NOT NULL,
PRIMARY KEY (id),
FOREIGN KEY (student_id) REFERENCES students (student_id),
FOREIGN KEY (course_id) REFERENCES courses (course_id)
);

Through the design of the above table, We can realize the correlation between students, teachers, classes and courses, and manage course selection records.

Of course, in the actual design of the school management system, in addition to the above basic tables, other related tables may also be involved, such as test score tables, classroom tables, school administrative department tables, etc. The specific table structure design needs to be adjusted and improved according to actual needs.

To sum up, this article introduces the MySQL table structure design guide for the school management system and provides corresponding table structure code examples. I hope it can be helpful to everyone in the development of the school management system. Of course, in practical applications, issues such as performance optimization and data security also need to be considered.
