SQL Real-World Projects: Building a Student Management System

Project Overview

A Student Management System stores information about students, courses, and their enrollments.

The system allows administrators to add students, assign courses, and track enrollment details.

• Manage student personal information.
• Maintain course details.
• Track which students are enrolled in which courses.

Database Design

Designing the database involves creating tables for Students, Courses, and Enrollments.

Each table has specific columns and primary keys to uniquely identify records.

• Students table stores student_id, name, email, and date_of_birth.
• Courses table stores course_id, course_name, and credits.
• Enrollments table links students and courses with enrollment_date and grade.

Creating Tables with SQL

Use SQL CREATE TABLE statements to define the structure of each table with appropriate data types and constraints.

Primary keys ensure each record is unique, and foreign keys maintain referential integrity.

• Define student_id as an integer primary key.
• Use VARCHAR for text fields like name and email.
• Set foreign keys in Enrollments to reference Students and Courses.

Sample SQL Code

Below is an example of SQL statements to create the Students, Courses, and Enrollments tables.
