Saxo Bank has adopted a data mesh architecture to address integration challenges and deliver data-driven insights across the organization. The company has leveraged Confluent, Flink, and MongoDB to build a scalable and flexible data fabric. By federating domain ownership and centralizing oversight, Saxo aims to ensure that data is accessible, understandable, and consumable by various stakeholders. The data mesh architecture is technology-agnostic, with Protobuf serving as the foundational layer for data domains. To address discoverability, Saxo has implemented a self-service platform that provides a consistent user experience across domains, utilizing metadata and metrics to surface data assets and their relationships. By embracing Protobuf's strong message types and field-level annotations, Saxo aims to improve data product usability and drive continuous improvement through ongoing curation of domain models. The company also emphasizes the importance of standards, referencing external coding schemes and business terms to ensure consistency and accuracy in data representation.
