Advanced SQL Series - Solving Real World Data Problems with SQL

Overview:

In my pursuit of advancing my SQL skills, I embarked on an exciting and challenging journey with the intermediate, project-based course led by Jess Ramos. This course wasn't just about learning SQL; it was about applying it to solve real business problems, mirroring scenarios faced by modern tech companies.

My Experience & Growth:

Throughout this course, I tackled eleven business-focused coding challenges, each designed to simulate a real-world problem. These challenges were not just exercises in coding but also in critical thinking and strategy. The course allowed me to explore and practice:

Analyzing product performance using Common Table Expressions (CTEs). Data transformation and decision-making logic with the CASE statement. Integrating multiple data streams with UNION for comprehensive analysis. Navigating hierarchical data structures through self-joins. Addressing complex queries with advanced window functions. Each challenge sharpened my SQL programming skills and deepened my understanding of its practical applications in a business context.
