Following are few use cases where this pattern will be a right fit:

• Manage master data: Inconsistency in shared data such as customer address may have a high business impact.
• Merge other applications to an existing system: In case of application mergers, data from other system needs to be merged into existing system. There might be cases where the same data is tagged with different identifiers in the individual application databases. An MDM implementation can help resolve these differences.
