Daniel Power provides an excellent online overview of decision support systems at dss.cba.uni.edu/isworld/dss.html. At www.uky.edu/BusinessEconomics/dssakba/periodcl.htm, you'll find an extensive list of links to DSS Web sites maintained by Clyde Holsapple and Andrew Whinston, authors of the excellent textbook, Decision Support Systems: A Knowledge-based Approach (The West Group, 1996). Another excellent text, available in many university libraries, is Decision Support Systems and Intelligent Systems by Efraim Turban and Jay E. Aronson (1998).
