D Correct answer
Explanation

OLAP (Online Analytical Processing) databases used for data warehousing contain multiple table types. Staging tables hold raw data before processing, Dimension tables store descriptive attributes (like time, geography, product), and Fact tables store quantitative metrics and foreign keys to dimensions. All three are fundamental components of a dimensional data warehouse. The star or snowflake schema architecture requires both fact and dimension tables, and staging tables are essential for the ETL loading process.

AI explanation

An OLAP (analytical) database schema typically contains staging tables for raw incoming data, dimension tables describing the business entities (time, product, customer, etc.), and fact tables holding the measurable, numeric transaction data. Since a real OLAP warehouse design uses all three layers together, 'All of the above' is the most complete and correct answer.
