define data warehousing
Solution
Data warehousing is a system used for reporting and data analysis, and is considered a core component of business intelligence. They are central repositories of integrated data from one or more disparate sources. They store current and historical data in one single place that are used for creating analytical reports for workers throughout the enterprise. The data stored in the warehouse is uploaded from the operational systems. The data may pass through an operational data store and may require data cleansing for additional operations to ensure the quality of the data before it is used in the DW for reporting.
