8.1 Introduction to Information Skills and Systems
An information system has a purpose in that it addresses the need(s) of a group or an individual. It performs the information processes of collecting, organising, analysing, storing/retrieving, processing, transmitting/receiving and displaying.
Information processes involve computer and non-computer activities and they have a social impact on the environment in which they operate.
Australian scientists are involved in the design of information systems.
8.2 Tools for Information Processes
Information processes and tools affect participants within the information system and people beyond it, giving rise to social and ethical issues.
Australian scientists are involved in research to improve the tools involved in information processing
8.3 Planning, Design and Implementation
New information systems are created when old systems do not adequately meet the need of users of the information system, or when a need exists that could be met by an information system.
Australian scientists are researching technologies to advance the design and implementation of information systems.
9.4.1 Option 1 - Transaction Processing Systems
Information systems that collect, store, modify and retrieve records of transactions are transaction processing systems. A transaction is an event that generates or modifies data that is eventually stored in an information system.
Transaction processing systems meet record keeping and event tracking needs.
Australian scientists are involved in the research and design of transaction processing systems
9.4.2. Option 2 - Decision Support Systems
When the task that end user(s) need to perform involves decision-making, the information system required is a decision support system. Decision support systems use combinations of models, analytical tools, databases and automated processes to assist decision-making.
Automated processing is achieved via intelligent systems that either focus on rules, such as expert systems, or pattern detection in data, such as neural networks.
Australian scientists are involved in research and development of decision support systems.
9.4.3 Option 3 - Automated Manufacturing Systems
Manufacturing information systems support the production process in a number of ways, including the tracking of inventory, record keeping, the scheduling of production and carrying out production.
Automated manufacturing systems have computerised controls built into the manufacturing equipment.
Data is gathered through sensors and following some processing, a signal is sent to an actuator, a device that performs some mechanical action.
Australian scientists are involved in research and development of automated manufacturing systems.
9.4.4 Option 4 - Multimedia Systems
Multimedia systems are information systems that combine the different types of media.
Australian scientists are involved in research and development of multimedia systems
