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

Adding the second assignment for the SQL module

What did you learn from the changes you have made?

I learned how to write advanced SQL queries, how to develop a logical model for a database and ethical issues related to developing new technologies.

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

Some question for Section 3 could be done by different ways, but I decided to follow a way that would help in debugging such as the use of CTEs to improve readability and modularity of the code.

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

Yes, it was challenging to combine different concepts from previous sessions, but it was very helpful to figure out how to apply these concepts in a situation similar to real-life problems.

How were these changes tested?

I run every Query using the DB Browser SQLlite software
