Design and implement the database layer for the RoadPulse AI – Smart Road Maintenance & Monitoring System. This module will be responsible for storing and managing user information, complaint records, maintenance assignments, and status updates efficiently.

Objectives Design a scalable and secure database structure. Implement MongoDB collections and schemas. Ensure data integrity, validation, and efficient querying. Tasks

1. Database Architecture Design Analyze system requirements and design the database structure. Define relationships between users, complaints, and maintenance staff. Prepare an Entity Relationship Diagram (ERD).
2. User Collection

Create a collection for storing user information:

Full Name Email Phone Number Password (encrypted) User Role (Citizen, Maintenance Staff, Admin) Account Status Created Date 3. Complaint Collection

Complaint ID Complaint Type Description Location Coordinates (Latitude & Longitude) Image URL Complaint Status Priority Level Submission Date User Reference 4. Maintenance Staff Collection

Create a collection for maintenance worker details:

Worker ID Name Contact Information Assigned Complaints Work Status Department Information 5. Database Validation Implement schema validation using Mongoose. Define required fields and data types. Prevent duplicate records where necessary. Add custom validation rules. 6. Database Connectivity Configure MongoDB Atlas connection. Create reusable database connection module. Manage environment variables securely. 7. Performance Optimization Create indexes for frequently searched fields. Optimize queries for complaint tracking and reporting. Ensure efficient retrieval of complaint and user data. 8. Documentation Document all collections and schema structures. Provide sample records and field descriptions. Prepare database setup instructions for the team.
