Which statement best describes a data dictionary in a Clarity data model?

• A. A catalog of user roles and permissions for the data warehouse.
• B. A guide for data visualization standards.
• C. A dictionary of data elements that stores only technical definitions with data types.
• D. A metadata repository describing each data element, including name, data type, allowed values, business meaning, source, constraints, and lineage.

Answer: (D)

A data dictionary in a Clarity data model is a metadata repository that describes each data element with comprehensive context: its name, data type, allowed values, business meaning, source, constraints, and lineage. This combination gives both technical details and business understanding, showing not just what a field is, but what it represents, where it comes from, how it’s constrained, and how it flows through the data pipeline. It supports governance, data quality, and consistent interpretation across users and systems. The other options miss important aspects: one describes security roles, another focuses on visualization standards, and the third limits itself to technical definitions, not the broader metadata and lineage that a data dictionary provides.
