Difference between DataStore Object (DSO) and InfoCube in SAP BW

In SAP BW, DataStore Objects (DSOs) and InfoCubes are two key data storage components that are used for data modeling and reporting. Here are the main differences between them:

DataStore Object (DSO):

• DSOs are best suited for detailed, granular data at a lower level of aggregation.
• They can be used for real-time data acquisition and reporting.
• They support overwrite and additive data acquisition modes.
• They are more flexible for data transformations and business rules implementation.

InfoCube:

• InfoCubes are best suited for aggregated data at a higher level of granularity.
• They are optimized for query performance and complex reporting scenarios.
• They support star schema data modeling with dimensions and facts.
• They are more suitable for historical data analysis and trend reporting.

Ultimately, the choice between using a DSO or an InfoCube depends on the specific requirements of the data model and reporting needs within the SAP BW system.
