What is data harmonization?

Data harmonization is a standardized analysis process completed by the Department of Health and Human Services (HHS) to satisfy the requirements of the Digital Accountability and Transparency Act (DATA Act). The process identifies details about data elements reported to the Government and suggests ways to standardize, or harmonize, all data attributes across reporting mechanisms in the Federal grant life-cycle so information can be consistent across all forms and systems. The harmonized data elements proposed and hosted in the Common Data Elements Repository (CDER) Library move closer to Government-wide standardization.
