Project Name: SUHBA
Slogan: "Where Connections Come Alive"
Logo: 
SUHBA is a Java-based desktop chat application developed as part of the ITI 9-Month Professional Training Program. This project serves as a practical implementation of software engineering principles, demonstrating expertise in desktop application development, system architecture, and database design.
✔ JavaFX with FXML for a responsive, user-friendly UI
✔ JDBC with MySQL for secure and scalable database management
✔ RMI (Remote Method Invocation) for efficient client-server communication
✔ Singleton & MVC design patterns for scalability and maintainability
✔ SOLID Principles and interface-driven development for clean architecture
✔ AI Chatbot Integration Using Gemini API
✔ Concurrency & Multithreading for high-performance communication
✔ Secure Authentication & Data Protection
✅ One-to-One & Group Chat – Real-time messaging with text formatting and file sharing
✅ Status & Presence – Online/offline indicators, availability modes (Available, Busy, Away)
✅ Secure Authentication – User login via phone number & password validation
✅ AI Chatbot – Integrated with Gemini API for automated responses
✅ Admin Dashboard – Server-side management for monitoring and announcements
✅ Multi-Client Communication – RMI-based for secure, distributed networking
✅ Modern UI/UX – Developed with JavaFX, FXML, and CSS for a seamless user experience
Our mission is to provide a secure, scalable, and user-friendly messaging platform that enables seamless communication through one-to-one chats, group chats, file sharing, and advanced features like voice/video calls and chatbot integration. We aim to empower users with a reliable tool for both personal and professional communication.
To become a leading messaging platform that revolutionizes how people connect, collaborate, and share information. We envision a world where communication is effortless, secure, and enriched with innovative features that enhance user experience.
"Where Connections Come Alive"
Our slogan reflects our commitment to creating a platform that brings people closer, fostering meaningful connections through technology.
We use Trello and Discord for project management and team collaboration. These tools help us stay organized, track progress, and communicate effectively throughout the development process.
- Trello: Used for task management, sprint planning, and tracking project milestones.
- Discord: Used for real-time communication, team meetings, and discussions.
We use a calm and professional color palette to ensure a visually appealing and user-friendly interface. The colors are chosen to provide a clean and modern look while maintaining readability and accessibility.
- #F9F7F7: Very light gray (used for backgrounds and light mode).
- #DBE2EF: Light blue-gray (used for secondary elements and input fields).
- #3F72AF: Medium blue (used for primary buttons, accents, and highlights).
- #112D4E: Dark navy blue (used for text, dark mode backgrounds, and headers).
- Backgrounds:
#F9F7F7for light mode,#112D4Efor dark mode. - Text:
#112D4Efor primary text,#3F72AFfor accents. - Buttons:
#3F72AFfor primary buttons,#DBE2EFfor secondary buttons. - Borders/Dividers:
#DBE2EFfor subtle borders and dividers.
You can view the color palette on Color Hunt.
Our system follows the Model-View-Controller (MVC) design pattern, ensuring modular, clean, and scalable development.
| Layer | Responsibilities |
|---|---|
| Model | Business logic, database access (JDBC, DAO). |
| View | JavaFX UI, dynamic updates using FXML. |
| Controller | Handles user interactions and updates the view based on model data. |
✅ Separation of Concerns – Clean division between UI, logic, and data
✅ Scalability – Easily extendable with new features
✅ Testability – Supports unit testing with mock implementations
To optimize performance and prevent redundant instances, we use the Singleton Pattern for:
✅ Database Access – Ensuring a single connection instance
✅ RMI Server Instance – Managing distributed connections efficiently
✅ Configuration Management – Centralized settings handling
The application uses a secure and scalable database to store:
- User profiles and credentials.
- Chat history and messages.
- File transfer logs.
- Server statistics and activity logs.
This section provides an overview of the database schema for the SUHBA Chat Application. The schema is designed to support user management, messaging, group chats, contacts, and administrative functionalities.
For a visual representation of the database schema, refer to the following diagram:
The SQL script for creating the database schema can be found at:
Relative Path: mysql.sql
✔ Indexing on frequently searched fields (userId, phone, email)
✔ Foreign Key Constraints for data integrity
✔ Normalization (3NF) to eliminate redundancy
✔ SQL Injection Protection with Prepared Statements
🚀 Result: Secure, scalable, and efficient database management.
🔹 Scene Builder for intuitive UI layout
🔹 CSS Styling for a clean, modern interface
🔹 Dark & Light Mode Support for accessibility
✔ Real-time Chat Updates – Messages appear dynamically
✔ Smooth Animations – Enhances interactivity
✔ Drag & Drop File Sharing – User-friendly media sharing
✔ Keyboard Shortcuts – Quick navigation for power users
🚀 Outcome: A clean, intuitive, and engaging user interface.
The client UI will provide an intuitive interface for users to interact with the chat application. Details will be added soon.
