Power BI DAX Data Modeling ETL

πŸ“Œ Table of Contents


Project Overview

This project is a Power BI case study for AtliQ Hardware, a multinational company selling computers and accessories through channels like **Amazon, Flipkart, Croma, and its own stores/e-store.

AtliQ Hardware faced challenges in international markets due to intuition-driven decisions. While the competitors are leveraging data-driven decision to make profit. To stay competitive, AtliQ has decided to take data-driven decision approach. The goal of this project was to build a unified reporting solution in Power BI across Finance, Sales, Marketing, and Supply Chain to empower stakeholders with data-driven insights.

The model integrates data from SQL + Excel, with over 1.5M+ records, and uses a custom fiscal year (Sep–Aug) for accurate reporting.


Tasks Performed

πŸ”Ή 1. ETL & Data Cleaning (Power Query)

  • Connected to multiple data sources including SQL Databases and Excel Workbooks.
  • Removed duplicates, handled null values, standardized column names, and ensured data consistency.
  • Created calculated columns for business logic (e.g., fiscal year alignment, category grouping).
  • Ensured data quality checks by validating numbers against benchmark/reference values.

πŸ”Ή 2. Data Modeling & Relationship Building

  • Designed a star schema with 15+ tables (fact & dimension).
  • Built relationships between sales, customers, products, regions, and targets.
  • Created a custom Dim_Date table with fiscal year mapping (Sep–Aug) and defined Q1–Q4 periods for reporting.
  • Ensured proper filter propagation across dimensions for accurate reporting.

πŸ”Ή 3. KPI Development (DAX Measures)

  • Built Net Sales, Gross Margin (GM), GM%, P&L Statement using advanced DAX functions.
  • Implemented Forecast Accuracy to compare actuals vs predictions.
  • Created variance measures to track performance vs targets.
  • Designed Target Tolerance KPIs to highlight customers with high GM% variance for Sales team prioritization.

πŸ”Ή 4. Dashboard Design & Reporting

  • Developed Sales, Finance, Marketing, Supply Chain dashboards.
  • Created an Executive Dashboard – consolidated view of all critical KPIs for top-level decision making.
  • Added tooltips to show customer trends and insights on hover.
  • Built drill-through & drill-down features (e.g., from Region β†’ Country β†’ Customer).
  • Applied conditional formatting and business-focused visuals to make reports intuitive.

πŸ”Ή 5. Performance Optimization

  • Used DAX Studio to analyze query performance.
  • Optimized DAX measures (e.g., replacing row context with filter context where applicable).
  • Reduced dashboard refresh time for smoother user experience.

πŸ”Ή 6. User Adoption

  • Simplified navigation with bookmarks and buttons.
  • Added clear instructions and labels to improve accessibility for non-technical users.
  • Created a User Guide to explain dashboard usage.

Key Insights & Recommendations

  • LATAM region grew by ~58% β†’ despite small base ($3.16M), shows strong future potential.
    βœ… Recommendation: Increase investment in LATAM through partnerships, targeted promotions, and expanding distribution channels.

  • Absolute Forecast Error spiked in FY2021 β†’ indicating high fluctuations between under-forecasting & over-forecasting.
    βœ… Recommendation: Improve demand forecasting models by integrating historical sales + external factors (seasonality, promotions, competitor activity).

  • AtliQ reached Top 5 in overall market share (5.8%), marking a major competitive milestone.
    βœ… Recommendation: Focus on retaining top customers and strengthening supply chain to further climb the market ladder.
