What is mapping validation?

Mapping validation is the process of verifying that data mappings between two or more systems, databases, or data formats are correct and consistent. This ensures that information is transferred accurately and meets the required business or technical specifications. Mapping validation is crucial during data migration, integration, or transformation projects to prevent data loss, corruption, or misinterpretation. It typically involves checking field correspondences, data types, and transformation logic to ensure they align with project requirements.
