| | Business Intelligence/Data Warehouse is a repository of a central managed and integrated database containing data from the operational sources in an organization (such as SAP, CRM, ERP system). The database contains detailed, stable, non-volatile and consistent data which can be analyzed in the time variant. Data warehouses are designed to facilitate reporting and analysis which can be created or updated at any time, with minimum disruption to operational systems. The concept of data warehousing can be implemented with an ETL process (Extract – Transform – Load) using several database applications/tools such as Hyperion, Informix, Microsoft SQL, SAP-BI (Business Intelligence), etc. | | | |
