This book examines decision making in general, the translation of knowledge about decision making into a DSS model, and the actual programming of a DSS. In addition, it combines the theoretical underpinnings of the topic with practical application using tools and technology currently available. Topics are discussed on three levels: general theory, implications for DSS design, and code development. This approach provides readers with practical examples than can be adopted into systems design. The Second Edition has been completely updated to reflect new technologies as well as the demands upon technology that have evolved since the publication of the First Edition in 1996. The book utilizes a combination of Dreamweaver and Cold Fusion, which are both popular software products that follow industry standards. (The First Edition utilized Level 5 Object, but all references to the software have been removed as it is not deemed a viable tool any longer.) In light of the numerous advances in the field of DSS over the years, there are many topics throughout the book that have updated and revised. For example, data warehousing has increased substantially in importance since the First Edition, and this section has been completely revised. The topic of business intelligence has been added, and similarly, data mining coverage has been increased via additional discussion and examples. In addition, transnational corporations have become more prevalent and are addressed accordingly.
