For further details, please refer to IPT: Introduction to Decision Support Systems

1. Features and abilities it would need:

  • Ability to handle a wide range of media (text, numbers, audio, image, animation, video)
  • Capture devices for audio (microphones) and image/video (cameras)
  • Versatile analysis tools to sort, search, label, and visually represent data
  • Fast processing hardware
  • Straightfoward user interface

2. Computer systems are uniquely suited to human decision support systems because:

  • Computer systems are quicker than NCB solutions for almost all practical purposes (multiplication of 585413 and 978125 for example)
  • Computer systems are almost always physically smaller (compare a mobile phone to an address book)
  • Computer systems can be programmed to do tedious but fundamentally simple tasks (e.g. arithmetic)

3. The main drawbacks of computer systems:

  • They require an electricity supply to function
  • They are often more expensive for simple tasks in isolation (such as using a laptop only as a calendar when one could purchase a paper calendar)

4. Scenario:

  • You are going shopping, but you live in the countryside, and the nearest shopping centre would take five hours to get to. You therefore need to construct a complex list of things that you will need to buy.
    • You recall that some of your friends' birthdays are coming up, but you are not sure when they are or whose birthdays they are.
  • Therefore, you decide to use your special relational database to see whose birthdays are coming up soon. This same relational database also has information about what gifts your friends like.
    • Using this information, you are able to purchase the right items for the right people when you go shopping in the very remote shopping centre.
