Basic Database Operations

-- Create a new database
CREATE DATABASE YourDatabaseName;
USE YourDatabaseName;

-- Run any script from the repository
-- Example: Hospital Management System
-- Open and execute 'sql project.sql'

Lab Activities

The repository contains numbered lab activities that should be completed in sequence:

-- Start with lab_activity#1.sql for basic concepts
-- Progress through lab_activity#2.sql to lab_activity#8.sql
-- Each lab builds upon previous concepts
