Assignment two

[SereneMousaoui]

What changes are you trying to make? (e.g., adding or removing code, refactoring existing code, adding reports)

Adding code, markdown, and logical models

What did you learn from the changes you have made?

I learned a lot about sub-querying, improving logical models to minimize many-to-many relationships, and reflecting on AI and ethics.

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

There were many different approaches to the possible queries for the assignment 2 SQL file. I tried to incorporate different techniques intentionally. For one query, I made a temp table, and for another, a CTE using 'with' queries. I appreciate the opportunity to practice everything we learned in class with this.

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

YES! Especially for the last few queries. Getting it to output what I wanted and finding out where to start. I used a lot of googling and asking for advice from my SQL-professional friends.

How were these changes tested?

I tested directly in SQL

Great attempt, reviewed. Try to play with git flows to better understand how does it work.
