Overview

This project demonstrates a complete data pipeline using Databricks, showcasing how to extract data from an external url, transform it with SQL and Python, and load it into a structured format for analysis. The project includes a CI/CD setup for ensuring code quality, reproducibility, and testing. The pipeline identifies trends in alcohol consumption and drug use across different countries and age groups, with a focus on actionable insights from complex SQL queries.

Pipeline Overview

Data Pipeline Components:

• Data Source: drinks and drug use tables.
• Data Sink: Transformed data is stored in Delta tables on Databricks.
• Transformation: Fill in na and new features created
• Visualization: Analysis results are visualized using Python's Matplotlib and Seaborn.

Pipeline Steps:

1. Extract data from url.
2. Load data into a Databricks Delta table.
3. Apply ransformations for data aggregation and filtering.
4. Visualize the results and save plots.
