Question
__________describes the data contained in the data warehouse.
Question 15
Answer
a. Relational data
b. Metadata
c. Operational data
d. Informational data.
Solution
The correct answer is: b. Metadata.
Explanation:
Metadata refers to the data that describes other data. In the context of a data warehouse, metadata includes information about the structure of the data, the meaning of the data, how it is organized, and how different data sets relate to one another. This information is crucial for understanding and effectively utilizing the data stored within a warehouse.
Relational data refers to data that is structured in a relational format, operational data pertains to the data used in the day-to-day operations of an organization, and informational data typically refers to processed data that provides insights. Thus, the best choice is "Metadata."
