## Overview

The README describes a retail sales analytics workflow: raw CSV data is validated with Python, modeled in SQL Server, analyzed with advanced SQL, and presented in interactive Power BI dashboards. The repository tree contains only the README, so these are documented stages rather than verified source modules; paths and any implementation-level wiring are unavailable.
