This repository contains my individual problem set solutions for Harvard's CS50's Introduction to Databases with SQL course, offered through HarvardX / edX.
The course covers relational database design and the use of SQL to create, query, and manipulate data. Topics include:
- Querying and modifying data with
SELECT,INSERT,UPDATE,DELETE - Designing schemas and relationships (primary/foreign keys)
- Joins, subqueries, and views
- Indexes and query optimization
- Transactions and data integrity
- Working with SQLite and PostgreSQL

Each problem-set-X folder contains the assignment's SQL files, schema definitions, and any supporting queries or notes for that week's task.
These solutions are shared for personal reference and portfolio purposes.
