在创建高校成绩管理系统的基础管理模块时,我们通常会使用SQL的`CREATE TABLE`语句来定义各个实体表的结构。这里是一个基本示例,展示了如何为描述的问题创建相应的表:
```sql
-- 高校表 (universities)
CREATE TABLE universities (
id INT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
location VARCHAR(255),
founded DATE
);
-- 部门表 (departments)
CREATE TABLE departments (
id INT PRIMARY KEY,
university_id INT,
name VARCHAR(100),
FOREIGN KEY (university_id) REFERENCES universities(id)
);
-- 专业表 (majors)
CREATE TABLE majors (
id INT PRIMARY KEY,
department_id INT,
name VARCHAR(100),
FOREIGN KEY (department_id) REFERENCES departments(id)
);
-- 课程表 (courses)
CREATE TABLE courses (
id INT PRIMARY KEY,
major_id INT,
title VARCHAR(255),
credit_hours INT,
FOREIGN KEY (major_id) REFERENCES majors(id)
);
-- 班级表 (classes)
CREATE TABLE classes (
id INT PRIMARY KEY,
course_id INT,
year INT,
semester VARCHAR(10),
FOREIGN KEY (course_id) REFERENCES courses(id)
);
-- 教师表 (teachers)
CREATE TABLE teachers (
id INT PRIMARY KEY,
name VARCHAR(100),
department_id INT,
FOREIGN KEY (department_id) REFERENCES departments(id)
);
-- 教室表 (classrooms)
CREATE TABLE classrooms (
id INT PRIMARY KEY,
capacity INT,
location VARCHAR(255),
FOREIGN KEY (department_id) REFERENCES departments(id) -- 如果教室按部门分配,可以关联部门
);
-- 学生表 (students)
CREATE TABLE students (
id INT PRIMARY KEY,
student_number VARCHAR(16) UNIQUE,
name VARCHAR(100),
major_id INT,
class_id INT,
FOREIGN KEY (major_id) REFERENCES majors(id),
FOREIGN KEY (class_id) REFERENCES classes(id)
);
