Complaint Management System Using Java and MySQL

Complaint Management System Using Java and MySQL

The Complaint Management System is a web-based application developed to help organizations handle employee complaints in a systematic and organized manner. The project uses Java, JSP, Java Servlets, JDBC, MySQL, HTML, CSS, and Apache Tomcat 9.0 to provide a platform for submitting complaints, assigning engineers, updating complaint statuses, and monitoring resolution progress.

The system includes three primary user roles: Admin/HOD, Engineer, and Employee. Employees can register, log in, and submit complaints, while administrators manage complaint records and assign engineers. Engineers can view their assigned complaints and update their progress. This role-based approach helps organizations maintain complaint records and coordinate the resolution process efficiently.

What Are the Key Features of the Complaint Management System?

The project includes complaint submission, engineer assignment, complaint tracking, and user management features. Its functionality is divided into three main panels to support the different responsibilities involved in resolving complaints.

1. Admin/HOD Panel

The Admin/HOD panel provides centralized control over complaints and engineer records. Administrators can monitor reported issues and assign the appropriate engineers to handle them.

• Secure Login: Administrators can access the management panel using their login credentials.
• Complaint Management: View and monitor complaints submitted by employees.
• Engineer Assignment: Assign engineers to specific complaints for investigation and resolution.
• Engineer Management: Add, update, and remove engineer information.
• Department Management: Categorize engineers according to their departments and manage available personnel.

These features help administrators maintain an overview of reported complaints and coordinate the work of engineers responsible for handling them.

2. Employee Panel

The Employee panel allows employees to report problems and follow the progress of their complaints without depending entirely on manual communication.

• User Registration: Employees can register for access to the application.
• Login System: Registered employees can sign in using their credentials.
• Complaint Filing: Submit complaints with relevant information about the issue.
• Complaint Tracking: Check the current status of submitted complaints.
• Password Management: Change account passwords when required.

By providing complaint tracking, the system helps employees understand whether their reported issues are being processed or have been resolved.

3. Engineer Panel

The Engineer panel enables engineers to manage complaints assigned to them and record progress throughout the resolution process.

• Assigned Complaints: View complaints assigned by the Admin/HOD.
• Status Updates: Update complaint statuses, including in-progress and resolved.
• Resolved Complaint Records: Review previously resolved complaints.
• Password Management: Change account passwords when necessary.

These features help engineers organize their assigned work and maintain records of completed complaints.

How Does the Complaint Management System Work?

The system follows a structured workflow in which employees submit complaints, administrators assign engineers, and engineers update the status of assigned issues.

1. Employee Registration and Login: Employees register or sign in to access the employee panel.
2. Complaint Submission: The employee files a complaint with the relevant details of the problem.
3. Administrator Review: The Admin/HOD reviews the submitted complaint and assigns an engineer to handle it.
4. Engineer Processing: The assigned engineer reviews the complaint and updates its status while working on the issue.
5. Complaint Resolution: Once the issue is addressed, the engineer marks the complaint as resolved.
6. Status Tracking: Employees can check the status of their complaints, while administrators oversee complaint records and engineer assignments.

This workflow creates a clear process for complaint handling and helps each user understand their responsibilities.

Which Technologies Are Used in This Project?

The application combines Java web technologies with a relational database to process user requests, display dynamic pages, and store complaint information.

• Java: Provides the primary programming language for application logic.
• Java Servlets: Process incoming requests and handle application operations.
• JSP: Generates dynamic web pages for the application’s user interface.
• JDBC: Enables communication between Java application components and the MySQL database.
• MySQL: Stores application records, including user and complaint information.
• HTML: Defines the structure of web pages.
• CSS: Controls the appearance and layout of the interface.
• Apache Tomcat 9.0: Provides the server environment for running JSP and Servlet components.
