digital warehouse

A digital warehouse, also called an enterprise data warehouse, is a system designed to support data collection, data analysis, and reporting. A core component of business intelligence, a digital warehouse is a central repository containing both historical and current data from multiple sources to support the creation of analytical reports. Raw data is uploaded from operational systems and stored in a staging database. The integration layer collates the disparate data sets and stores it in an operational data store (ODS) database where it is accessed for analysis.
