Also known as: Format Standardization, Data Harmonization
The practice of transforming data into consistent formats and definitions to improve interoperability, quality, and reuse.
DESCRIPTION
Data standardization aligns formats, codes, and definitions across sources. It includes enforcing data types, units, naming conventions, and reference code lists. Standardization reduces ambiguity, improves quality, and enables reliable integration and analytics. It often leverages master/reference data and industry standards. Processes include profiling, mapping, rules, and validations. Over-standardization can limit flexibility for local needs; balance is required. Governance ensures controlled changes and adoption. In analytics, standardization enables consistent KPIs and cross-domain insights.
ALTERNATIVE DEFINITIONS
Wikipedia
Data harmonization is the process of bringing together data of varying file formats, naming conventions, and columns and transforming it into one cohesive data set.
Closely related concept emphasizing unifying disparate formats into cohesive data.
ISO 8000
ISO 8000 provides requirements for data quality and is applicable to master data, transactional data and product data.
Establishes formal requirements and guidance related to data quality and standards.
