Corporate Information Factory

Brief Description

EDW (enterprise data warehouse) - the EDW is the center of the Corporate Information Factory. The EDW contains data that is:

• granular
• integrated
• historical
• corporate

The data found in the EDW feeds data marts, exploration warehouses, data mining warehouses, and class IV ODS. In short the data found in the EDW serves as a foundation for all data warehouse and DSS processing.

The data found in the EDW is sometimes called the "single point of truth" for the corporation. The data is granular and non redundant and is at the basis of reconciliation of disputes when two or more people disagree as to a result obtained from analysis of the Corporate Information Factory.

The EDW is stored on both primary storage and alternative storage. The primary storage is almost always high performance disk storage. Alternative storage is near line or secondary storage.
