T3: S&R

posted Jul 20, 2010, 11:04 PM by Eddie Woo
Term 3 is here! By the end of these ten weeks, you will have completed the entire prelim course. That means we really have our work cut out for us. We're going to start by launching into the 'fourth' process: storing and retrieving.

You've already been introduced to this process, so I'm going to drop you right in the deep end and ask you to fill in the table below. The first column describes the three major reasons why storing and retrieving is carried out within an information system. In the other two columns, you are to provide real-life examples of this for (a) manual systems and (b) computer-based systems. Notice that for the first reason, I want you to provide three distinct examples (i.e. for three different processes - you have six to choose from).

Reasons for S&R
Example in manual system
Example in computer-based system
1. To allow the other processes to take place
2. To allow for a temporary halt in the system
3. Backup and recovery

The task above was brief, so that you can spend the rest of today's double-period making headway on your group project. By the end of today's lesson, you should have:
  • Have a draft of component 1a
  • Completed component 1b
  • Almost completed component 1c
  • Drafts of components 1d, 1e and 1f
  • A basic version of component 3
All of your progress with regard to these should obviously be documented on your group's register (component 4). Thanks class - I look forward to seeing your progress in the Group Project Hub! Less than two months to go now - get cracking now and get lots done now, because you won't want to focus on this project when your preliminary final exam comes up in week 7.
