What is the difference between an InfoCube and a DSO in SAP BW?

InfoCube: In SAP BW, an InfoCube is a multi-dimensional data storage structure that stores data in a star schema format. It is used for reporting and analysis purposes and stores aggregated and detailed data from various source systems. InfoCubes are typically used for analytical reporting and support complex queries.

DSO (DataStore Object): A DSO in SAP BW is a two-dimensional storage object that stores detailed and granular data from source systems. Unlike InfoCubes, DSOs store data in a flat structure without aggregation. DSOs are used for data staging, cleansing, and harmonization before loading the data into InfoCubes or other reporting objects.

Differences: InfoCubes are optimized for analytical reporting and aggregate data, while DSOs are used for detailed data storage and data staging. InfoCubes are designed for complex queries and reporting requirements, while DSOs are used for data integration and transformation processes.
