Applications

Main Topics of Study

A. General

  • Define package, program, application, program and data
  • Benefits and limitations of different data capture methods to the business and to the client
  • Data capture forms (screen and paper). In this case, an awareness that screen is an output device confirming inputs
  • Outputs (printed and screen). Selection of appropriate form of output. Billing layouts
  • Distinction between on-line direct access and batch runs
  • Process diagrams. Systems flowchart or Data flow diagrams could be used but a formal diagram is not expected – the requirements are that candidates are aware of the sequence of events including rectifying errors
  • Back-up systems needed including restart processes where a lengthy print run may fail in mid run because of a printer failure

B. Applications:

Thorough investigation of each of the following applications:

  • Mail order and customer accounts
  • Stock control
  • Supermarket sales
  • Library administration
  • Public utility companies’ administration
  • Hotel administration and bookings
  • Banking related to customer accounts
  • Club membership
  • Estate agency (real estate) administration

Such an investigation of each of the above applications should cover the aspects listed below.

  • Overall purpose of the application
  • The role of the people involved
  • The detailed format of the sources data for each aspect of the application
  • The method of data capture for each type of input – devices suitable for this
  • The processes that operate in the business – systems diagrams. Batch or on-line
  • The filing systems required including contents of each file and methods of organisation and access
  • The outputs that are produced
  • The devices required for each type of output
  • How each output will be used and possible follow-ups

Example Candidate Response Booklet

Example Candidate Response (ECR) Booklets are a source of crucial information for Centres and Candidates as they use real candidate responses. We ask Senior Examiners to comment on five or more responses in terms of why the mark was awarded with commentary about how to improve the answer (if necessary).
