What you’ll learn

• Write SQL queries confidently to create, read, update, and delete data (CRUD) across real-world relational databases like MySQL, PostgreSQL, and SQL Server
• Design normalized schemas, create tables, define keys and constraints, and model relationships
• Use intermediate to advanced SQL: JOINs, subqueries, window functions, CTEs, set operations, views, stored procedures, triggers, and transactions
• Optimize queries with indexes, execution plans, and performance tuning techniques, and work safely with transactions
• Analyze data with aggregations, grouping, rollups/cubes, date/time functions, and practical reporting patterns used in analytics and BI
• Apply SQL to real projects: building a mini data model, writing production‑style queries, and solving interview‑style challenges and case studies

Requirements

• No prior SQL experience is required; the course starts from absolute basics and gradually advances to expert topics
