Advanced SQL (Free Online Course) : Advanced SQL elevates database interaction from simple data retrieval to complex analytical processing, enabling developers to perform sophisticated calculations directly within the database engine. It moves beyond basic SELECT and JOIN statements to incorporate Window Functions—like RANK() and LEAD()—which perform calculations across related rows without collapsing them into a single result. A key pillar of this level is the use of Common Table Expressions (CTEs), which act as temporary, named result sets that transform long, nested subqueries into modular and readable code blocks. Proficiency also requires mastering performance tuning techniques, such as analyzing Query Execution Plans and optimizing indexes to handle massive datasets with minimal latency. Ultimately, Advanced SQL is the essential toolkit for data engineers and analysts tasked with building scalable data pipelines, complex reporting dashboards, and high-performance applications.
