Transforming corporate information into value through data warehousing and data mining

The purpose of this paper is to provide an introduction to some promising potential applications to turn the existing information within a corporation into a business advantage through data warehousing and data mining. The idea is to have a data warehouse system capable of accommodating diverse needs through analytical decision support usage. Roll up data from legacy transaction-based routine business operational systems have to be an integral part of the repository. In addition, data warehousing plans must be done in conjunction with rep-level strategies, and most importantly with the cooperation of the technical and other business entities within the corporation. An architecture to coordinate the evolution will be needed. Also, per implementation perspective, there are many synergies between intranet and data warehousing. In turn, intranet provides a quick and easy mechanism for external data sourcing, and facilitates information access by its users anywhere, at any rime, which is critical in making timely decisions.
