Decision Support and Data Warehousing: Challenges of a Global Information Environment

Abstract

This chapter is dedicated to the major managerial, organizational and technological aspects of development of data warehouses in a global information environment, when different external sources of information are available and potentially may have value for decision support and managerial analysis. It summarizes the major benefits that become available for businesses if they decide to integrate information from external sources into their data warehouses. It also introduces the overall organizational framework of development of data warehouses that are based upon the information from different external sources. Furthermore the author hopes that understanding of the framework introduced will not only inform practitioners (both information technology (IT) specialists and managers in different spheres of business) of new possible approaches to design of decision support systems but also assist in the improvement of approaches to decision-making procedures.
