What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)
I completed by adding the required written responses in the markdown file, designing two ER diagrams for the bookstore logical model, and writing the SQL queries for Sections 2 and 3.
What did you learn from the changes you have made?
I learned how to design a logical data model and think more carefully about relationships between tables, including one-to-many, many-to-one, and many-to-many relationships. I also gained more practice with intermediate and advanced SQL concepts.
Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?
Not really. It was already a lot for me to practice the basic ones.
Were there any challenges? If so, what issue(s) did you face? How did you overcome it?
It was alright in general. The model design took a lot of time, but I made it in the end.
How were these changes tested?
The SQL queries were tested in DB Browser for SQLite. I ran the queries individually, checked the outputs, and revised them when needed to ensure they matched the assignment instructions.
