Introduction

Decision Support Systems have evolved over the past three decades from simple model-oriented
systems to advanced multi-function entities. During the 1960s, most Decision Support Systems
were fairly based on powerful (and expensive) mainframe computers which provided managers
with structured, periodic reports. MIS theory developments during the 1970s saw Decision
Support Systems evolve into more elaborate computer-based systems that supported production,
promotion, pricing, marketing and some logistical functions. By early 1980s Decision Support
Systems enjoyed more interests from academics and the framework for Decision Support Systems
was greatly expanded by the end of the decade. It was only during the 1990s that a paradigm shift
occurred in Decision Support Systems and more complex systems, which incorporated, advanced
database technology and client/server capabilities, were emerging from many areas in business
processes. As many organizations started to upgrade their network infrastructure, object-oriented
technology and data warehousing started to make its mark on Decision Support Systems.
