Building on the Beginner Course, this course covers the tools and concepts that separate casual SQL users from professionals. You'll learn to create reusable database logic with views, stored procedures, and triggers. You'll understand how to design efficient schemas through normalization, manage data integrity with transactions, handle errors gracefully, write advanced queries with subqueries and CTEs, and speed up your databases with indexes.
Each chapter includes practical SQL examples across MySQL, PostgreSQL, and SQL Server where syntax differs. By the end, you'll be equipped to build and maintain production-quality databases.
