What is DWH?

DWH stands for Data Warehouse. It is a central repository of integrated data from one or more disparate sources. Data warehouses 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 typically uploaded from the operational systems such as marketing, sales, and accounting. It goes through data cleansing, transformation, and cataloging before being stored in the data warehouse. Data warehouses are commonly used for business intelligence and analytics to facilitate decision-making.
