python -m venv venv

# Activate environment (Windows)

venv\Scripts\activate

# Or on Linux/Mac: source venv/bin/activate

# Install dependencies

pip install -r requirements.txt

```

### 2. Data Preparation

Download the sample dataset from Kaggle:

- **Dataset**: [Customer Sales Data](https://www.kaggle.com/datasets/kyanyoga/sample-sales-data)

- **Location**: Place `SampleSalesData.csv` in `data/raw/` directory

### 3. Execute Pipeline

```bash

# Run the complete ETL pipeline

python pipeline.py

# Expected output:

# 🚀 OPERATE OPTIMA ETL PIPELINE STARTING

# 📥 PHASE 1: DATA EXTRACTION

# 🔄 PHASE 2: DATA TRANSFORMATION  

# 💾 PHASE 3: DATA LOADING

# 🎉 ETL PIPELINE COMPLETED SUCCESSFULLY!

```

## 📊 Data Processing Flow
