SQL Practice Database

This is a work-in-progress open-source SQL practice project.

What This Project Will Include

• Database schema: Tables for departments, employees, products, customers, orders, and more.
• Sample data: Realistic data for all tables.
• Practice queries: A variety of SQL exercises, from basic SELECTs to more advanced queries.
• Learning resource: A place to experiment, learn, and share SQL knowledge.

Set Up the Database

• Open your preferred MySQL client (e.g., MySQL Workbench, DBeaver, or MySQL command line).
• Execute the SQL scripts in 000.sql to create the sql_practice database, define all the tables, and populate them with sample data.

Database Schema & ER Diagram

The detailed database schema and entity-relationship diagram are now available in DATABASE_SCHEMA.md.
Please refer to that file for a full description of tables, columns, relationships, and the ER diagram.
