Multiple Choice

A data analyst explores and notes definitions, data types, and relationships between tables. What does this scenario describe?

This describes metadata management. When a data analyst describes definitions, data types, and how tables relate to each other, they’re documenting the meaning and structure of the data assets—information about the data itself. That collection of definitions, data types, and relationships is precisely what a metadata repository stores. It serves as a centralized catalog that helps with data governance, consistency, and discovery, so people understand what each piece of data means and how it connects across the system. The other options fit different needs. A data lake is about storing raw data in its native form for flexible use, not specifically documenting definitions or table relationships. A data warehouse focuses on integrated, processed data prepared for reporting and analysis, not on cataloging metadata. Data profiling analyzes actual data values to assess quality and characteristics, which is about the content of data rather than the metadata that describes it.
