UofT-DSI | SQL - Assignment 1

[ruokun-ai]

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

Added SQL queries to meet assignment requirements, including data selection, filtering, calculated fields, CASE logic, date handling, temporary table creation, record insertion, and aggregation with GROUP BY.

What did you learn from the changes you have made?

Strengthened my ability to write SQL for data extraction, transformation, and aggregation, and gained hands-on experience with functions such as strftime().

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

Considered alternative approaches such as using date ranges (BETWEEN) instead of strftime().

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

Encountered syntax issues with INSERT and handling date functions. Resolved them by searching in stack overflow and correcting query structure.

How were these changes tested?

Executed all queries in SQLite, verified successful execution, and validated outputs against expected results.
