The objective of this guide is to facilitate the study of my friend’s level of understanding of the subject matter and at the same time provide an insight of how I view the subject and my personal understanding of the subject, in relation to the style of the examination questions.
*disclaimer* All content in this bible is either copied directly from study guide, Jack koh’s ISORG bible, internet knowledge. It is just a summary and all information are based on Jeffrey’s personal opinion/interpretation. Use is at your own risk. Overview of this ISORG BIBLE
I’ll start of the ISORG bible with what I deemed important terms that will be used in the course of this subject. I’ll first give definitions from the subject guide as this will definitely be accepted by the examiners. Next I’ll give further definitions I found from websites/ Jack Koh’s notes to provide further insight and better understanding. I’ll then give explanations and also examples if possible of the term used. Most of the example will probably be from Jack Koh’s study package or even his ISORG bible unless I actually have the time to source out more. BUT beware, if I do add further examples that I found out online, those are examples that I myself believe is appropriate, they may or may not even be correct so use those at your own risk. After all the definitions and explanations, I’ll try and include a brief summary of Jack Koh’s bible showing paragraphs that I find useful. I’ll italics and ‘quote’ the paragraphs or phrases that I sourced from his bible. At the end, I have also suggested a few articles that I feel are MUST reads for better ideas of how to answer questions. Finally, I just hope this ISORG bible is actually of even any use to anyone.
Information systems are sets of interrelated components that collect or retrieve, process, store and distribute information to support decision-making, co-ordination, control, analysis and visualization. (UOL-SG) Information systems are implemented within an organization for the purpose of improving the effectiveness and efficiency of that organization. Capabilities of the information system and characteristics of the organization, its work systems, its people, and its development and implementation methodologies together determine the extent to which that purpose is achieved. (Wikipedia.org) The study of information systems is normally premised on the assumption that information systems are socio-technical systems. Socio-technical aspects encompass both technical and social variables. There are three perspectives or lenses with which to look at the role played by systems and networks in organizations namely data model (technical), decision-making model (cognitive) and transaction-cost model (behavioural). Examples of information system includes
* Date warehouses (Page 5)
* Enterprise resource planning
* Transaction processing system
* Management information system
* Decision support system
* Executive information system
Information and communications technology
Information and communications technology (ICT), just like it’s’ name, refers to the different technology used in information processing/transferring and also technologies that aid in communication. Examples of ICT includes internet, extranet, cloud computing, wireless communication, TCP/IP, GPS, online video conferences, ipad, iphone, servers, databases, hardware and software infrastructure. (Jeffrey) *I gave up on this chapter especially regarding the hardware and software and so is unable to come up with a detailed write out about this.*
The data model is a model that describes in an abstract way how data are represented and interrelated in an information system, a database management system or even a business organization. In particular, this model focuses on data flows which can actually help the analyst design a new system or even the entire organization. (UOL-SG) A data...
