SQL Fundamentals
Master SQL fundamentals in 2 days. You'll start by understanding the history of data management systems and the role of relational databases today. Then you'll learn to manipulate your data: insert, update, delete, and most importantly query with SELECT. Progressively, you'll master WHERE, ORDER BY, LIMIT clauses, then aggregations with GROUP BY and HAVING. You'll discover the power of joins to combine multiple tables, subqueries and Common Table Expressions (CTEs) to structure complex queries. Finally, you'll cover database design: entity-relationship modeling, normalization, primary and foreign keys, indexes and views. Hands-on training with 60% labs on real-world scenarios.
