Advanced Reports
Report 1: Academic Resource Distribution
Data requirements idea/concept title
Faculty and Staffing Overview by University
Data requirements description
This report summarizes how many professors and subjects are assigned to each faculty within every university. It utilizes existing relationships between the University, Faculty, Professor, and Subject tables to provide a distribution matrix of academic resources.
Solution SQL
SELECT u.Name AS university_name, f.Name AS faculty_name, COUNT(DISTINCT p.Id) AS total_professors, COUNT(DISTINCT s.Id) AS total_subjects FROM University u JOIN Faculty f ON u.Id = f.University_Id LEFT JOIN Professor p ON f.Id = p.Faculty_Id LEFT JOIN Subject s ON f.Id = s.Faculty_Id GROUP BY u.Name, f.Name ORDER BY total_professors DESC;
Solution Relational Algebra
γ_{u.Name, f.Name, COUNT(p.Id) → total_professors, COUNT(s.Id) → total_subjects}
(University ⋈_{u.Id = f.University_Id} Faculty ⋈_{f.Id = p.Faculty_Id} Professor ⋈_{f.Id = s.Faculty_Id} Subject)
Report 2: Student Activity and Advising Monitor
Data requirements idea/concept title
Student Engagement Across Enrollment and Advice Modules
Data requirements description
This report combines two separate many-to-many relationship structures (Student_Subject and Advice) into a unified diagnostic view. It displays each student's name, index, and home faculty along with the count of distinct subjects they are actively enrolled in and total academic advising sessions logged.
Solution SQL
SELECT s.Name || ' ' || s.Surname AS student_name, s.Student_Index, f.Name AS faculty_name, COUNT(DISTINCT ss.Subject_Id) AS enrolled_subjects, COUNT(DISTINCT a.Professor_Id) AS advice_requests FROM Student s JOIN Faculty f ON s.Faculty_Id = f.Id LEFT JOIN Student_Subject ss ON s.Id = ss.Student_Id LEFT JOIN Advice a ON s.Id = a.Student_Id GROUP BY s.Id, s.Name, s.Surname, s.Student_Index, f.Name ORDER BY enrolled_subjects DESC;
Solution Relational Algebra
γ_{s.Name, s.Surname, s.Student_Index, f.Name, COUNT(ss.Subject_Id) → enrolled_subjects, COUNT(a.Professor_Id) → advice_requests}
(Student ⋈_{s.Faculty_Id = f.Id} Faculty ⋈_{s.Id = ss.Student_Id} Student_Subject ⋈_{s.Id = a.Student_Id} Advice)
Advanced Reports AI Usage
Name of AI service: Gemini
URL: https://gemini.google.com/
Type of service: Free Tier
Final result: The AI was utilized to troubleshoot Trac Wiki rendering syntax issues, cross-reference query definitions with strict production schema tables, and format relational algebra groupings safely.
Results in details:
- Debugging Wiki Syntax: After identifying formatting block constraint errors within the wiki parser engine, I used the AI to refine character spacing configurations and clean up block parameters.
- Schema Verification: I used the AI to audit my outer join parameters. It helped verify that I correctly mapped standard casing names (like using Student_Index instead of index_number, and Student_Id instead of stud_id), bringing the reports into perfect synchronization with my DDL code files.
- Relational Algebra Formatting: The AI assisted in writing out formalized relational algebra sequences using projection, conditional theta-joins, and aggregate extensions ($\gamma$) that accurately express the logic of our underlying SQL queries.
