Querying multidimensional data with independent fact and dimension pipelines combined at query time

摘要

Separate subsystems are dedicated to handle fact and dimension data storage and retrieval in an optimized manner. Each subsystem acquires, processes, and stores its data separately in a manner appropriate to the characteristics of that data. A query engine combines the data from each subsystem at query time. When a user queries the system, the query engine interacts with each of the subsystems to fetch the data needed to generate a single result set.
