Capstone: School Database System

1What is a School Database System?✨

A School Database System manages information about students, teachers, classes, and grades. It helps schools organize data efficiently, making it easier to access and analyze.

2Why Learn SQL for School Databases?🎯

• ✓ Essential for data management in educational institutions
• ✓ Enables advanced querying for insights
• ✓ Supports scalability for growing school data
• ✓ Prepares you for real-world database challenges

3Designing the Database💡

First, we need to create tables for our database. Here’s how you can create a simple structure:

CREATE TABLE Students (
    student_id SERIAL PRIMARY KEY,
    name VARCHAR(100),
    grade_level INT
);

CREATE TABLE Teachers (
    teacher_id SERIAL PRIMARY KEY,
    name VARCHAR(100),
    subject VARCHAR(50)
);

4What You'll Query This Lesson🚀

• ✓ Retrieve student information
• ✓ Find teachers by subject
• ✓ Calculate average grades
• ✓ Join data from multiple tables

5Sample Queries🔍

Now, let's run some queries to work with our data. For example, to get a list of all students in 10th grade:

SELECT * FROM Students WHERE grade_level = 10;

6To find the subjects taught by a specific teacher:⭐

SELECT subject FROM Teachers WHERE name = 'Mr. Smith';

7Project Overview🧩

For your capstone project, you will design a complete School Database System. This includes creating tables, inserting data, and writing complex queries that can provide valuable insights, such as student performance trends and teacher workloads. Let’s get coding!
