## 📂 Project Overview

This project focuses on analyzing coffee shop sales data to uncover patterns, identify trends, and provide insights for business optimization.

## 🔑 Key Objectives

- Analyze overall sales performance, including **total sales, orders**, and **quantities sold**.

- Explore **sales trends over time**, including weekday vs. weekend performance.

- Identify the **best-performing products** and **top-selling store locations**.

- Visualize peak sales hours and days using advanced **Power BI visualizations**.

🛠️ Tools & Techniques

**1. Power BI**

- Created interactive dashboards with slicers, heatmaps, and KPIs.

- Visualized sales performance across different dimensions like time, product category, and location.

- Used DAX for calculations like Month-over-Month (MoM) growth.

  

**2. SQL**

- Extracted and transformed data from raw transactional tables.

- Performed complex aggregations, joins, and trend analysis.

- Calculated MoM growth, daily/hourly trends, and top-performing entities using advanced SQL queries.

## 📊 Dashboard Features

**1. KPI Metrics**

- **Total Sales**: $82K

- **Total Orders**: 17,314
