Using staging, integration, and access to accommodate the main functions, typical ETL data warehouses carry rapid operation in various organizational departments. In the first step, the staging layer or database stores raw information, which is extracted from the source and system that is not appropriate.
The second integration layer will combine different information sets. This is done by transforming records of the staging layer stored in the Database Store operational information. This integrated fact is then removed to another database, also known as data warehouses.
