Reference Data

Reference data forms a critical foundation for Data Quality and consistency in enterprise information systems. Unlike transactional or analytical data, reference data provides the standardized values and classifications that other data elements reference and depend upon.

Characteristics

Core Attributes

• Relatively stable and infrequently changed
• Widely shared across multiple systems
• Authoritative source for common values
• Critical for Data Integration and Interoperability Standards

Types of Reference Data

1. Internal Reference Data

   • Department codes

   • Organization Hierarchy structures
   • Internal status codes

2. External Reference Data

   • Country codes
   • Currency codes
   • Industry classification standards
   • Regulatory Compliance codes
