5. Master Pareto Analysis (80/20) in SQL Server | Advanced Window Functions & CTEs

Описание: Video Description: Unleash the full power of SQL to identify the "Vital Few" that drive your business! In this tutorial, we dive into the technical implementation of Pareto Analysis (the 80/20 rule) using SQL Server (SSMS).

This video is a core part of our "Pareto Analysis Series," where we solve the same business challenge across multiple platforms: Excel, DAX Studio, Power BI, SQL (this video), and Python.

Using a real-world dataset (Pareto.csv) , we will write a high-performance query to analyze customer revenue, identifying top contributors like Elizabeth Lincoln ($55,550) and Victoria Ashworth ($29,000).

💡 What you will learn in this session:

Common Table Expressions (CTE): Organizing complex logic into readable, modular blocks.
Window Functions: Mastering SUM() OVER() to calculate Cumulative Revenue.
ROW_NUMBER(): Efficiently ranking records to prepare for running totals.
FORMAT() Function: Ensuring your percentages and currency look professional in the final output.

The Pareto Logic: Calculating the running total percentage to hit that 80% threshold.
