Pillar No. 5: Information Warehousing
With an understanding of master information management and the key role it plays in managing master information assets in an enterprise, I now move to another important facility, information warehousing (traditionally known as data warehousing) in enterprise information management (EIM). Information warehouse is a consolidated system of records for all business information in an enterprise across business functions. It is a single version of truth that gives the business leaders a cross-functional view of enterprise performance. Building an information warehouse involves integrating data from numerous internal and in some cases external sources.
