https://github.com/jen2004/data-analysis-project-for-dvd-rental-business
For this project, I analyzed PostgreSQL's sample "dvdrental" dataset to answer the business question: "Which top three film categories had the most rentals each month?" I designed detailed and summary tables, implemented SQL queries with user-defined functions, triggers, and stored procedures, and automated data updates and refresh processes.
