Transform Data into Insights with SQL Skills

SQL is one of the most powerful tools for working with data, and this course is specifically designed to help you apply it in business analysis. We will start by connecting to a database and executing basic queries to answer common business questions, such as comparing sales month over month, identifying top-selling products, and calculating average prices by category. As you progress, you’ll learn to analyze customer behavior by calculating average order values (AOV), segmenting customers into new, frequent, and inactive groups, and identifying your most valuable customers using the Pareto Principle 80-20.

In the advanced segment of the course, you will discover how to build year-over-year (YoY) and month-over-month (MoM) comparisons, accumulations, running totals, and dynamic rankings that simplify performance visualization. We will explore strategic KPIs, such as differentiating between best-selling vs. most profitable products, identifying product cannibalization, and constructing a clear and actionable executive report. The course culminates in a mini practical project, where you will apply everything you’ve learned to decide which products to promote next month based on data.

This course will not only teach you SQL but also provide a practical framework for using data in strategic decision-making, blending theory with practice in real-world business scenarios. If you want to be someone who uses SQL to create impact in sales, marketing, and finance, this course is for you.
