Design and Build a Complaints Tracking System with SQL

Overview

Learners will analyze business requirements, design relational databases, and build a complete Complaints Tracking System using SQL Server and VB.NET through a hands-on, end-to-end case study. By completing this course, learners will gain practical experience in database design, application development, complaint workflow management, reporting, and system testing. This course guides learners step by step from understanding the purpose of a complaints management system to implementing a fully functional application. Learners will design normalized database schemas, establish relationships using primary and foreign keys, and implement the database in SQL Server. They will then connect the database to a VB.NET application to build complaint registration, assignment, tracking, search, and reporting features. What makes this course unique is its real-world, project-based approach. Instead of isolated concepts, learners work on a single case study that mirrors how complaint management systems are built in professional environments. The course emphasizes both technical skills and practical workflow logic, helping learners understand how databases and applications work together in real business scenarios. By the end of the course, learners will be able to confidently design, develop, and evaluate a database-driven application suitable for real-world complaint tracking and management systems.

Syllabus

Complaints Tracking System Foundations

This module introduces learners to the Complaints Tracking System case study by explaining its business purpose, workflow, and core requirements. Learners explore how customer complaints are structured as data and how foundational database entities are identified and designed to support effective complaint management using SQL Server.

Database Relationships and Schema Finalization

This module focuses on refining the database design by establishing relationships, enforcing referential integrity, and applying normalization principles. Learners then implement the finalized schema in SQL Server and prepare the project environment for application development using VB.NET.

Complaint Registration and Processing

In this module, learners develop the functional workflows of the Complaints Tracking System, including database connectivity, complaint registration, assignment logic, and status management. The emphasis is on building reliable application logic that supports real-world complaint processing.

Administration, Reporting, and Finalization

This final module covers administrative features, complaint search and filtering, reporting, and system validation. Learners complete the case study by building role-based interfaces, generating analytical reports, and performing final testing to deliver a production-ready Complaints Tracking System.
