Some Essbase applications contain large volumes of detailed data that users frequently summarize across dimensions such as Product, Market, Time, Customer, and others.

BSO is appropriate when the application needs a broader combination of aggregation, data entry, and business processing. You will learn more about those capabilities as you continue planning the application in terms of calculation and aggregation requirements.
You'll learn about these considerations in Apply Business Logic with Calculations.
