Data Warehouse is a data management system designed in order to support and enable Business Intelligence (BI) activities. These warehouses intend to perform analyses and queries and also contain a large amount of data. This data is generally derived from numerous sources like transaction applications and application log files.
A data warehouse consolidates and centralizes large volumes of data from a wide range of data sources. It has analytical capabilities that help organizations to extract business information from the data and make improved decisions. With time, it builds historical records that may be of no use to the Business Analysts and Data Scientists.
