Amityadav08/PROJECTS_SETS2_SUBMISSION — reverse-engineered prompt

Build me a complete data analysis and machine learning portfolio repository that I can share as a submission or on GitHub.

I want it to include separate projects for SQL, Python analytics, and Python machine learning. The SQL work should cover things like a university database and healthcare analysis, with realistic tables, useful queries, and clear reporting. The Python analytics projects should analyze retail, financial, and employee resignation data, with charts, business insights, and practical recommendations. The machine learning project should use retail data for prediction, classification, customer grouping, and forecasting.

Please make everything clean and easy to run, with simple README files inside each project explaining what it does, what data file is needed, how to install requirements, and how to run the scripts. Add comments in the code so a reviewer can understand it. The goal is for this to feel like a polished data science portfolio, not just random scripts.
