In which scenario, you would like to go for materializing dimension?
Correct Answer
A. To increase speed.
Explanation
Materializing dimensions involves creating physical tables or structures to store pre-aggregated data, which can significantly improve query performance and speed. By materializing dimensions, the data can be accessed directly without the need for complex calculations or joins, resulting in faster data retrieval. This approach is particularly useful when dealing with large datasets or complex queries that require frequent access to aggregated data. It does not directly affect memory size but can indirectly contribute to reducing memory usage by minimizing the need for on-the-fly calculations.
13.
What are different storage mode options?
Correct Answer
A. MOLAP, HOLAP and ROLAP.
Explanation
The different storage mode options in this context are MOLAP, HOLAP, and ROLAP.
