  3. Learning Objectives • Understand DSS configurations. • Learn characteristics and capabilities of DSS. • Understand DSS components. • Describe structure of DSS components. • Understand how DSS and the Web interact. • Learn the role of the user in DSS. • Understand DSS hardware and integration. • Learn DSS configurations.

  4. DSS • A DSS is a methodology that supports decision-making. • It is: • Flexible; • Adaptive; • Interactive; • GUI-based; • Iterative; and • Employs modeling.
