What did you learn from the changes you have made?

I learned a lot from reading "When Databases Get to Define Family". I hadn’t previously thought about how database design can reinforce and has reinforced social hierarchies and inequalities around the world.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

I was considering making the query output more comprehensive or cleaner. For example, in the second question of the aggregate section, I debated whether to show the actual amount of money that everyone spent at the market or to calculate it quietly within the HAVING statement. I think both approaches have their pros and cons, and the choice is very question- and context-driven.

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

The codes were relatively straightforward. I was able to compare the results from the output and manual calculation from the 'Browse Data' tab to verify the results.

How were these changes tested?

Run sql codes in DB Browser
Check changes using git status, commit the change, and then push the change
