Hello, and thanks for stopping by! 👋
This repository showcases SQL projects I’ve completed as part of my data analytics learning journey. The projects focus on data modeling, data transformation, and analytical querying using real-world datasets. Each project is designed to answer meaningful business or analytical questions and demonstrate practical SQL skills.Feel free to explore the projects below, review the queries, and reach out if you have any feedback or questions.
🏥 Medical Insurance Cost Analysis
Data: Medical Insurance Cost dataset (Kaggle)
Focus: Healthcare cost drivers, data modeling, and analytical insights
In this project, I analyzed medical insurance costs to understand what factors drive higher healthcare charges. I designed a star schema with fact and dimension tables (age group, BMI category, region, smoker status, and sex) to support scalable analysis.The project demonstrates SQL data modeling, transformations, joins, aggregations, indexing, and insight generation.
🤖 Top AI Tools: Popularity & Valuation
Data: Top AI Tools: Popularity & Valuation (Kaggle)
Focus: Technology trends, popularity analysis, and market valuation
This project explores the AI landscape by analyzing the popularity and estimated valuation of leading AI tools. Using SQL queries, I ranked AI tools to identify which platforms are most widely adopted and which receive the highest market valuation.This project highlights ranking, filtering, aggregation, and comparative analysis using SQL.
