Data warehouse is used to store, manage and retrive required/historical data efficiently. The data warehouse is used for hitorical data and center of the business intelligence environment.

BW is use to analyze historical data (also data warehouse but for all modules like hr, pm, sd, mm etc.) and plus it comes with reporting tools like BEx Analyzer, WAD, Report Designer to produce report.
