Modern digital experiences on top of critical core systems
Arborline Bank’s card platform supported decades of products, customer histories and risk controls. Core systems remained reliable systems of record, but new mobile experiences depended on complex point-to-point integrations and specialist mainframe releases.
Payment volume continued to grow while customers expected immediate alerts, controls and personalised service. Fraud teams also needed a current view of transactions, devices, disputes and customer interactions before an analyst—or an AI assistant—could make a useful recommendation.
An operational data layer for every channel
The bank created a new operational data layer on SelectiveDB. Change streams from core systems populate a governed customer-and-card view that is exposed through reusable services to mobile, web, servicing and partner channels.
The same data model supplies fraud-investigation tools with real-time transaction context and links to supporting evidence. Selective Cloud provides encryption, private connectivity, workload isolation and automated resilience while core records remain in their existing systems of record.
Payment services that can evolve independently
Arborline now processes 16 terabytes of operational payment data each day and supports 65 production microservices. At peak, the platform handles 5.8 million events per hour while preserving sub-second access for customer channels.
Reusable services doubled the pace of feature releases across mobile and servicing experiences. Fraud analysts also receive a consolidated case context in seconds rather than navigating multiple legacy screens.
