III. PROPOSED SYSTEM

The proposed lost and found web application aims to streamline the process of reuniting lost items with their owners by leveraging modern web technologies. The system is designed to be user-friendly, secure, and efficient, ensuring a seamless experience for all users. The following outlines the key components and functionalities of the system.

1. System Architecture: The application is built using Next.js, a React framework known for its server-side rendering (SSR) and static site generation (SSG) capabilities. This ensures optimal performance and SEO benefits. The backend is powered by Prisma ORM interfacing with MongoDB, providing a scalable and flexible database solution.
2. User Authentication: User authentication and authorization are handled by NextAuth, which supports various OAuth providers for secure login options. This integration ensures that user credentials are managed securely, enhancing overall trust and security within the application.
3. User Interface: The front-end of the application is designed with Tailwind CSS, a utility-first CSS framework that allows for rapid and responsive UI development. The design focuses on simplicity and ease of navigation, ensuring that users can quickly list or search for lost and found items.
4. Core Functionalities:

• Listing Items: Users can create listings for lost or found items by providing a title, description, category (lost or found), and contact information. Each listing is stored in the MongoDB database.
• Searching Items: Users can search for lost or found items using keywords, categories, and other filters. The search functionality leverages MongoDB’s indexing capabilities for fast and efficient data retrieval.
• Contact Information: To facilitate direct communication, each listing includes contact information. This approach simplifies the process of reuniting lost items with their owners by allowing direct contact between the finder and the owner.

1. Data Management: The use of Prisma ORM ensures efficient data handling and interactions with the MongoDB database. Prisma’s type-safe query capabilities enhance developer productivity and reduce the likelihood of runtime errors, leading to a more robust application.
2. Security Measures: Security is a critical aspect of the proposed system. NextAuth provides secure authentication mechanisms, while Prisma ensures safe database transactions. Additionally, the application incorporates standard security practices such as HTTPS, data validation, and protection against common web vulnerabilities (e.g., SQL injection, XSS).
3. Performance Optimization: By leveraging the SSR and SSG features of Next.js, the application delivers fast load times and improved performance. These features are particularly beneficial for content-heavy pages, ensuring a smooth user experience even under high load conditions.
4. Mobile Responsiveness: Given the significant number of users accessing web services via mobile devices, the application is designed to be fully responsive. Tailwind CSS facilitates the creation of a mobile-friendly design, ensuring that the application functions well across various devices and screen sizes.
5. Scalability: The architecture of the proposed system is designed to be scalable. MongoDB’s sharding capabilities and Next.js’s static generation ensure that the application can handle increasing amounts of data and user traffic efficiently.
6. User Feedback and Improvement: The system includes mechanisms for collecting user feedback, which is crucial for continuous improvement. Regular updates and enhancements based on user feedback ensure that the application remains relevant and useful to its user base.
