Phase 6: Complex Database Reports, SQL, Stored Procedures, and Relational Algebra

Overview

This phase demonstrates how the Wedding Planner database can be used for advanced reporting, analytical queries, stored procedures, and relational algebra representation.

The goal of this phase is to show that the database is not used only for storing data, but also for extracting meaningful information such as financial summaries, guest statistics, venue utilization, RSVP conversion rates, and overall wedding performance.

What We Cover

• Complex SQL reports across multiple related tables
• Stored procedures for reusable reporting logic
• Relational algebra representation of the reports
• Aggregation, grouping, filtering, and calculated fields
• Financial, operational, and RSVP-based analysis
• Performance considerations for complex reports

Report Scenarios

Scenario	Description
Budget vs Actual Expenditure Analysis	Compares planned wedding budget with actual vendor costs
Venue Capacity Utilization Analysis	Analyzes guest attendance compared to venue capacity
Event RSVP Conversion Rate Analysis	Measures RSVP response rates and attendance conversion
Synthesis and Performance Considerations	Combines analytical dimensions and explains optimization strategies

Summary

Phase 6 introduces advanced database reporting for the Wedding Planner Management System.

The implemented reports use multi-table joins, aggregate functions, conditional aggregation, temporal calculations, stored procedures, and relational algebra expressions.

These reports help analyze wedding costs, venue usage, RSVP efficiency, and overall event planning performance.
