Processing & Decision Support

Recall that processing refers to any method by which data can be manipulated in different ways to produce a new value or result. Under this definition, every calculation, inference and judgement made by a decision support system falls under the category of processing.

In a classwork post, answer the following questions:

1. A device like a video camera is primarily a collecting device; however, designers have found it useful to incorporate other processes into it for convenience (e.g. storing and retrieving). Collecting is the central process, while the others are peripheral. Explain why processing is the central process of decision support.

HSC Electives

English (3U, 4U)
    Ancient History
    Modern History
    History Extension
    Japanese (B,C)
Maths (2U, 3U, 4U)
Visual Arts

2. Describe a shell and outline the reasons why programmers might include one in their decision support system. 

3. Contrast the decision support that is provided by (a) a spreadsheet with (b) an inference engine.

4. With regard to forward chaining and backward chaining:
    (a) Outline each of the processes.
    (b) For each, identify two examples where it would be suitable where its counterpart would not be.
    (c) On the right is a table of all the HSC electives that can be chosen in years 11 and 12. Use both forward and backward chaining to come up with a list of alternative solutions for the subjects you will choose for next year, and thoroughly document the process.

5. Answer questions 4 and 5 on page 206 of the textbook.

Important Note: due to the Australian Intermediate Mathematics Olympiad (AIMO) taking place on 13th August, your trial exam has been rescheduled to the next day - Friday 14th August. The time remains the same.
