Many sources, one consumption view.
Govern a shared semantic and consumption layer across source platforms instead of making one physical migration the only route to consistency.
Operating pattern
An enterprise data estate can span operational systems, warehouses, lakehouse platforms, files, and specialized applications. The sources may use different definitions for the same business object while consumers still need a coherent view.
A physical consolidation program is one architectural option, but it is not the only way to establish a governed consumption contract.
Capability pattern
Assign each source a clear role, resolve shared business entities, and place a governed semantic layer above the sources. Lineage, quality expectations, access rules, and stewardship remain visible across the full path to consumption.
Migration decisions can then be made dataset by dataset without withholding a common meaning layer until every source has moved.
What the pattern enables
The pattern connects data and trust. Consumers work against consistent definitions, while owners can trace each value to its source, transformation, quality rule, and access boundary.
