Seminar Topic : Data Warehousing

Introduction: 

Data Warehouse is a database used for reporting. The data is uploaded from the operational systems for reporting. The data may pass through an operational data store for additional operations before it is used in the DW for reporting.

A data warehouse maintains its functions in three layers: staging, integration, and access. Staging is used to store raw data for use by developers (analysis and support). The integration layer is used to integrate data and to have a level of abstraction from users. The access layer is for getting data out for users.
