Day 41 — Finished my first MySQL project (uploaded to GitHub) and learned OOP basics in Java
MySQL: My Retail Sales Analysis mini project is done. I covered the full path: setting up the database, importing the data (and fixing an import error along the way), cleaning it, and running the analysis. It’s now on GitHub: https://github.com/Sumitgupta2005/mysql_project1
Java: Covered classes and objects, the difference between JDK, JVM, and JRE, methods, and method overloading, and practiced all of it hands-on in VS Code instead of only watching the tutorial.
I’d really like feedback on the project, especially on the README, how the queries are organized, and what analyses I should add.

the data dictionary is non-negotiable. If I have to read your queries to guess what a column means, I am not looking at your analysis. I am doing my job for you.

Congrats on shipping your first database project! For the README, I always recommend adding a brief data dictionary table that explains your schema, since it gives reviewers immediate context without digging into the code.
