In the age of digital transformation, libraries are no longer just physical spaces, but intelligent, AI-driven ecosystems. LibraAI is a state-of-the-art digital library management system built with Object-Oriented Design Principles and enhanced by Google Cloud AI services, offering:
- 🔒 Secure authentication and role-based access
- 📖 Smart cataloging and real-time tracking
- 🔍 Advanced search and personalized recommendations
- 🤖 AI tools: summarization, translation, read-aloud, and intelligent Q&A
The legacy Nexus Library System (now evolved into LibraAI) faced critical issues post-upgrade:
- ❌ Duplicate/missing records caused availability confusion
- 🔓 Uncontrolled access to restricted collections
- 📦 Mismatched borrow records vs availability
- 🔍 Ineffective search and irrelevant suggestions
To overcome these, our engineering team rebuilt the system using a clean, scalable architecture powered by modern OOP design patterns and Google AI.
- ✅ Modular Backend using OOP and 9+ design patterns (Factory, Singleton, Strategy, etc.)
- 📊 Real-Time Book Status: Borrowed, Reserved, Available, Under Review
- 🤖 AI-Powered Services via Google Cloud APIs:
- ✨ Gemini API: Intelligent document summarization and assistant Q&A
- 🌐 Google Translate API: Real-time multilingual content translation
- 🔊 Google Text-to-Speech API: Seamless read-aloud for accessibility
- 🌐 Web Scraping Pipelines for open-access resources:
- E-Books & Journals → Open Library, Google
- Research Papers → Semantic Scholar
- 📚 Role-Based Access Control:
- Guest, Student, Researcher, Faculty, Librarian
- Librarians manage physical inventory
- 🔎 Advanced Search Engine:
- Strategy-based: Keyword, genre, author, type
- 📩 Notifications & Reminders using Observer Pattern
- Factory Pattern: Dynamic creation of
LibraryItemtypes (E-Book, Journal, Research Paper, Audiobook, Physical Book) - Singleton Pattern: Shared
LibraryDatabasefor consistent access control - Builder Pattern: Configurable library items with optional metadata
- Facade Pattern: Unified interface for user operations (borrow, return, reserve)
- Decorator Pattern: Extend item features like priority access
- Observer Pattern: Real-time alerts (due dates, availability)
- Strategy Pattern: Swappable search logic and recommendation engine
- Command Pattern: Support for undo/redo borrowing actions
- State Pattern: Book condition/status transitions (Available → Reserved → Borrowed)
