The organising information process prepares the data for use by other information processes. - It does this by structuring and representing the data in a form suited to the needs of the subsequent information process.
- We discussed the meaning of structuring and representing as it applies to the organising process earlier; it may be worthwhile reviewing that section.
- The organising process does not alter the actual data, rather it modifies the way it is structured and represented; the data itself is still the same.
- For example, when text is entered into a word processor it is organised by structuring it into a string of individual characters where each character is represented using a binary code (commonly an extension of the ASCII system).
- The data is still the same characters, words, sentences and paragraphs that the user entered; it has just been organised into a suitable form for the word processor.
Organising takes place just before, just after or even as an integral part of other information processes. - This is particularly the case in regard to collecting, displaying, storing and retrieving, and transmitting and receiving.
- During and after collecting data must be organised to modify its format to suit the requirements of subsequent information processes.
- During and prior to displaying information it must be organised into a form that can be used and understood by the display device. When storing data it is first organised into a format suitable for storage and subsequent retrieval.
- Transmitting involves the reorganisation of data to conform to the rules required for communication; receiving data involves reversing this organisation process.
- The ability to analyse and process data efficiently depends on the way the data is organised.
- For example, when a page of text is scanned each character is part of an image.
- This method of organising text is inappropriate if you wish to subsequently edit the text itself.
- The scanned image of the page of text needs to be reorganised into individual characters in preparation for editing.
- In this example optical character recognition (OCR) software could be used to organise the image into a series of characters that can be used by a word processor.
- The selection of software that is able to organise data appropriately is critical to the success of all computer-based information systems.
- If the data is organised appropriately then vital analysing and processing tasks can be completed more efficiently
Our focus in this stem is on the strengths and weaknesses of various different software tools, the aim being to make informed decisions when selecting software tools to use within an information system. The method a software application uses to organise data determines the type and efficiency of processing that can take place. We therefore need to understand how different software applications organise data. We shall examine examples of the following types of software: - paint and draw software for images.
- mixing software for audio.
- video editing software for video and audio.
- word processors and desktop publishing for text, images and numbers.
- spreadsheets for numeric.
- database software that organises data into tables.
- website creation software that uses hyperlinks to organise data for web pages.
- presentation software that arranges data on slides.
We then consider some tools used to organise non-computer data and finally consider a number of social and ethical issues associated with the organising process. |
