What does the term 'reference data' signify in the context of DAMA-DMBOK?

The term 'reference data' in the context of DAMA-DMBOK signifies data that provides context for other data, often used for classification. Reference data is essential for maintaining data integrity and consistency across systems and analytical processes. It typically consists of values that categorize and define other datasets, such as standardized codes, lists, or classifications that serve as points of reference.

For example, a reference dataset might include country codes, product categories, or unit measures. These elements help to ensure that data is interpreted uniformly across various applications and business contexts. By providing a structure for data classification, reference data enhances data interoperability and contributes to effective data management practices.

This function distinguishes reference data from other types described in the other choices. Sensitive data, transactional records, and constantly changing data serve different purposes and do not align with the characteristic role of reference data in providing classification and context.
