This project aims to develop an online banking system with a distributed architecture and centralized database storage. The system allows both internal and external access with proper login. It was developed with a client-server model in mind using HTML5 for the front end, Java for programming, and MySQL for the backend database. Hardware requirements include a minimum of 256MB RAM, 40GB HDD, and Windows OS. The system integrates all browsing center activities and provides management and customers with necessary information for monitoring activities without physical file movement. It allows adding new account modules and uses digital signatures to make the cards more secure.
