Assignment two

[SilviMargarian]

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

I am adding SQL codes.

What did you learn from the changes you have made?

I learned how to use window functions, cross joins, and insert/delete/update data.

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

No, I wasn't thinking of any other approach.

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

Yes, I struggled with cross joins (not intuitive to me somehow) and the update question. I had to visit lecture material for more clarity and google for more complex examples. The lecture didn't cover many complex examples.

How were these changes tested?

I wrote and tested my codes in SQLite first, then transferred them to the assignment.sql file.
