Final answer:
Aggregating data for computation in one or more dimensions is called roll-up. It is used in business intelligence to summarize detailed data into broader categories. This contrasts with drill-down, which provides more detailed data views.
Step-by-step explanation:
The action of aggregating data so that it can then be computed in one or more dimensions is known as roll-up. Roll-up is a process in data analysis that involves summarizing or combining detailed data into broader categories to provide a greater level of generalization. This is the opposite of drill-down, which involves breaking down aggregated data to view more detailed levels of data. Roll-up is commonly used in business intelligence and analytics, especially in the context of data cubes where one may want to view the data at a higher level of aggregation, such as moving from data about specific products to product categories.
