Types of Digital Banking Architecture
Different types of digital banking architecture are employed by financial institutions to offer online services to their customers. Some of the most prominent ones are:
1. Client-Server Architecture
Such architecture can have a very centralized server that provides services to its clients via the internet or through mobile application services. It can be an interface through which access can be gained to account balances, transfer of funds, payment, etc. All information in the account for the customer will be stored securely within the central server. It will include transaction history and personal information regarding the customer. Logging in with credentials will provide access to such data by customers. Hence, sensitive information remains accessible only by authorized users. The centralization of the system makes data integrity and more accessible use in upkeep and maintenance.
2. Peer-to-Peer Architecture
A primarily decentralized network can be used as a banking architecture for facilitating transactions. In this case the system is made peer-to-peer, which means that it is a client-server system without a central server, since all communication made will be done via clients.
