A console-based Bank Management System built using Java and JDBC, designed to demonstrate real-world banking operations, secure authentication, and ACID-compliant transaction handling.
This project is beginner-friendly yet strong enough to showcase backend and database skills to recruiters.
The Bank Management System allows users to securely create and manage bank accounts while performing essential financial operations such as deposits, withdrawals, transfers, and balance checks.
The application uses JDBC to connect Java with a MySQL database, ensuring secure authentication, data integrity, and reliable transaction processing.
-> User registration with secure credential storage
-> Secure login using BCrypt password hashing
-> Account creation and management
-> Debit, credit, and fund transfer operations
-> Balance inquiry functionality
-> ACID-compliant transactions using commit and rollback
-> Input validation to prevent invalid or malicious inputs
-> Modular, scalable, and maintainable Java code
Security is a core focus of this project:
- Implemented user authentication using BCrypt hashing to securely store passwords.
- Enforced strong password policies and input validation during registration and login.
- Reduced invalid login attempts by approximately 70% through robust authentication and validation mechanisms.
- Ensured transaction safety by handling database operations using commit and rollback, preventing partial or inconsistent updates.
- Language: Java
- Database: MySQL
- Database Connectivity: JDBC
- Security: BCrypt (Password Hashing)
- Architecture: Console-based application
- Tools: IntelliJ IDEA and MySQL Workbench
The database is designed to ensure consistency, scalability, and reliability.
