Complaint Management System using Node.js and MongoDB

Complaint Management System is a web-based application that enables the users to lodge complaints and track their status. The system will be built using Node.js, which is a fast, scalable and efficient server-side JavaScript framework, and MongoDB, which is a popular NoSQL database. The system will be user-friendly and easy to use.
Objectives:
To provide a platform for users to lodge complaints and track their status
To enable the admin to manage the complaints and assign them to the respective departments
To provide real-time updates to the users on the status of their complaints
To maintain a centralized database of all the complaints lodged
Project Features:
User registration and login
User can lodge a complaint and attach relevant documents
User can view the status of their complaints
Admin login
Admin can view all the complaints lodged
Admin can assign the complaints to the respective departments
Admin can update the status of the complaints
Real-time updates to the users on the status of their complaints
Technology Stack:
Node.js
MongoDB
Express.js
HTML/CSS
JavaScript
Bootstrap
Methodology:
The project will follow the Agile methodology, which involves iterative and incremental development. The project will be divided into sprints, and each sprint will deliver a working software increment. The requirements will be gathered from the stakeholders, and the software will be developed in an iterative manner.
Conclusion:
The Complaint Management System using Node.js and MongoDB will provide an efficient and user-friendly platform for users to lodge complaints and track their status. The system will be built using the latest technologies, and it will follow the Agile methodology for development. The system will be scalable, fast and efficient, and it will help the admin to manage the complaints more effectively.

Detailed Project Description

Complaint Management System using Node.js and MongoDB digitises the day-to-day records and workflows of an organisation so data is stored once, retrieved instantly and reported accurately.

How It Works
1. Role-based login separates admin, staff and end users.
2. Each module (records, bookings, transactions, reports) provides full CRUD operations with validation.
3. Data lives in a relational database with proper relationships between entities.
4. Reports and search views summarise the stored information.

Technology Roles
- Java
- JavaScript
- MongoDB
- Node.js

Implementation Steps
1. Define requirements and draw the ER / class diagram and screen flow.
2. Set up the environment (Java, JavaScript, MongoDB) and create the project skeleton.
3. Design the database schema / data model and seed it with sample data.
4. Implement the core modules with validation and role-based access where needed.
5. Build the user interface and connect it to the backend / data layer.
6. Test each module (unit + manual), fix edge cases and secure inputs (SQL injection, XSS, auth).
7. Prepare documentation, screenshots and a demo build.

Key Features
- Role-based access
- CRUD modules
- Search and filters
- Reports / export
- Validation and error handling

Expected Output
On completion the student will have a multi-user application with organised records and printable/exportable reports.

Deliverables
- Complete source code with comments
- Database schema / data model and screen flow
- Project report with screenshots and results
- Demonstration-ready build
