As promised, we're launching into new territory. So far, we've treated decision support systems as if they are a big amorphous blob, all with basically the same purpose and characteristics. But - as you may have noticed when we were looking at clinical DSSes - there are several different types or categories of DSS, and they vary in complexity. We're going to look at four of these types - three today, and the fourth one next lesson.

  1. Spreadsheets
    (a) Describe the kinds of analysis supported by a spreadsheet.
    (b) Identify one example each of situations/decisions that would be supported (i) effectively by a spreadsheet or (ii) ineffectively by a spreadsheet.

  2. Databases
    Explain how a relational database can support decision-making in a way that a spreadsheet cannot. (eg)

  3. Expert Systems
    (a) Contrast between experts and expert systems.
    (b) Outline some of the difficulties in designing and implementing an AI-based DSS.
    (c) Account for why expert systems would be designed to be domain-specific.
