Library Management System (System Design Project)

📌 Overview

This repository contains a Library Management System (LMS) developed strictly for academic and system design purposes.
The project was created to apply and demonstrate Software Engineering concepts, SDLC, Agile methodology, and UML/System Design diagrams — not as a real-world or production-ready application.

⚠️ Disclaimer:
This system is a conceptual and educational project only.
It is not intended for real-life deployment, commercial use, or production environments.

🎯 Project Objectives

• Apply Software Development Life Cycle (SDLC) phases in a practical scenario
• Follow Agile methodology with sprint-based development
• Design and analyze system models and diagrams
• Implement basic CRUD operations conceptually
• Understand system architecture using MVC pattern

---

🛠️ Tech Stack (Academic Use)

• Backend: Laravel (PHP)
• Database: MySQL
• Frontend: Blade Templates + Tailwind CSS
• Architecture: MVC (Model–View–Controller)
• Version Control: Git & GitHub

📐 System Design Artifacts

This project includes detailed system design documentation, such as:

• ✅ Use Case Diagram
• ✅ Activity Diagram
• ✅ Class Diagram
• ✅ Sequence Diagram
• ✅ Context-Level DFD (Level 0)
• ✅ DFD Level 1
• ✅ ER Diagram
• ✅ UI Mockups

These diagrams are provided to demonstrate design thinking and system modeling, not production implementation.

🔄 Development Methodology

• Agile + SDLC (Hybrid Approach)
• Sprint-based development
• Incremental feature delivery
• Continuous review and refinement

Example Sprints:

• Sprint 1: Project setup & authentication design
• Sprint 2: Book management & borrowing logic
• Sprint 3: Dashboard & UI mockups
• Sprint 4: Testing & documentation

---

🧪 Testing Approach

Testing was performed to validate conceptual correctness, not production reliability.

• Unit Testing (CRUD logic)
• Integration Testing (Controller–Model flow)
• UI Testing (Navigation & flow)
• Performance considerations (basic)

Tools Used: PHPUnit, Postman, Browser Console

---

🚫 Limitations

• No real-world security hardening
• No scalability or load testing
• No production deployment setup
• Simplified authentication & authorization
• Intended for learning, evaluation, and demonstration only

---

📚 Learning Outcomes

• Hands-on experience with SDLC & Agile
• Practical understanding of system design diagrams
• MVC architecture comprehension
• Team collaboration using GitHub
• Translating theory into structured system design

---

📄 Documentation

Detailed system design, diagrams, and explanations are available in the Project Report (PDF) included in this repository.

📎 References

• Laravel Documentation
• PHP Official Docs
• MySQL Documentation
• Tailwind CSS Documentation

🧠 Final Note

This project was developed purely for educational and system design practice as part of a university course.
If you’re reviewing this repository, focus on the design decisions, diagrams, and methodology, not production readiness.
