How would you generate a report showing the top five scoring students, including three tables, with the condition that students have the same score in a subject?

To generate such a report you would typically use a combination of window functions, aggregation, and joins. First, identify the top five scores per subject using a window function: SELECT student_id, subject, score, RANK() OVER (PARTITION BY subject ORDER BY score DESC) AS rnk FROM student_scores; Then filter rnk <= 5. If you need to handle ties (students with the same score), you can use RANK() or DENSE_RANK() to include all students who share the same score. Next, join this result with the student details table to pull names, grades, etc. Finally, format the output into three tables: 1) a summary table of top scores per subject, 2) a detailed table of student information, and 3) a cross‑reference table linking students to subjects. In a reporting tool you would create three separate sheets or panels, each driven by the same underlying query but filtered or grouped differently. The key is to use window functions for ranking, handle ties with RANK/DENSE_RANK, and join to dimension tables for full context.
