In an operative BW system, the volume of data increases constantly. Constant changes to business and legal requirements mean that this data must be available for longer than was previously the case. Since keeping a large volume of data in the system affects performance and increases administration efforts, we recommend that you implement a data aging strategy.
Advantages of a data aging strategy:
Reduced costs for managing and saving data
Improved performance of the BW system
Efficient storage of historic data for comprehensive enterprise data warehousing
You have loaded data to your InfoProvider, possibly over a long period of time.
Information Lifecycle Management allows you to classify data according to how current it is and archive it or store it in near-line storage.
