Data Federation/Evidence
Method evidence record

Data federation is an approach to integrating data from heterogeneous, autonomous, distributed databases without requiring centralized storage. Formalized by Sheth and Larson in 1990, federated systems provide a unified interface to query multiple independent sources while preserving their autonomy and existing schemas.
