Data Mesh and Fabric Reference Architecture For Digital Banking
Decentralized Data Ownership and Federated Governance
Modern banks generate more data than they can centrally manage. This reference model introduces the Data Mesh, where data is treated as a "product" owned by specific business domains (e.g., the "Mortgage Team" owns and maintains mortgage data).
The technical framework utilizes a Data Fabric to provide a virtualized layer over disparate data sources (SQL, NoSQL, and Cloud Buckets), allowing for cross-domain analytics without the need for expensive and slow ETL (Extract, Transform, Load) processes. This ensures that the bank’s AI models have access to high-quality, real-time data for hyper-personalized customer offers.
