High-Level Design | System Design | Online Banking System
High-level design mainly focus on the overall architecture of the Online Banking System, defining the interaction among its major components. It includes
System Architecture
The Online Banking System includes essential additives consisting of the User Interface, Payment Gateway, Database, Authentication Service, Notification Service, Transaction Processing Service, Fraud Detection Service, and Logging and Monitoring Service. Communication is secured thru HTTPS, and interaction amongst components is facilitated by means of way of RESTful APIs. Real-time updates are enabled thru Websockets.
The system is designed for scalability, using horizontal scaling to make certain excessive availability and deal with improved masses. Security measures encompass HTTPS for constant data transmission, encryption for sensitive statistics like credit card statistics, and tokenization for more desirable protection. Availability is maintained through load balancing for visitors distribution and redundancy mechanisms for immoderate availability.
Data Flow
The payment process starts with a user-initiated pay request dispatched from the User Interface to the Payment Gateway. The Payment Gateway validates the request and forwards it to the Authentication Service, which verifies consumer credentials and performs important authorizations. Valid transactions proceed to the Transaction Processing Service, interacting with the Database to replace user account balances.
Transaction Logging and Auditing
In the High-Level Design (HLD), an quintessential issue is the incorporation of a sturdy transaction logging and auditing device. This system ensures that each one essential activity inside the Online Banking System are recorded for later analysis, auditing, and debugging. The Logging and Monitoring Service performs a relevant position in to capturing and storing unique logs of transactions, user interactions, and system activities.
