  1. Information Processes & Technology (IPT) Introduction to Information Skills and Systems

  2. IPT - Topics • Information Systems in Context • Information Processes • Social and Ethical Issues • Traditional Stages in Developing a System • Complexity of Systems • Rules of People Involved in Systems Development • Collecting • Organising • Transmitting and Receiving • Displaying

  3. Information Technology • Chapter 1 – Page 3

  4. Question? • What is Information Technology? • How has digital communication improved the transfer of data? • Describe the recent changes in banking that have resulted from Information Technology • What are some advantages and disadvantages of Information Technology? • List some ethical issues that have or may occur by the Information Technology • Explain what and why you use Information Technology?

  5. Information System • Information systems are systems which provide information to users. The term "information system" would normally refer to a computer based system using a DBMS. • A DBMS is a program which creates and manages a database. • A database is the file that is then created by a DBMS. • Database Management System (DBMS) is a software that enables a database to be created, edited and maintained as well as to be stored and searched to extract information

  6. Information System CONT... • Main Components of Information System • Lower box the information system affects and is affected by the information processes • The Information System is surrounded by a particular environment

  7. Information System CONT...

  8. Components Of Information System • Environment – Everything that is influenced by the Information System • Purpose – For what need & whom is the information system designed • Information Systems – Users, individuals, IDPO, computerised & non-computerised • Information Processes – Computerised such as access the internet & non-computerised such as listening to the news • Participants – People who carry out information processes with the information system • Date/Information – Raw materials of information going in & coming out as processed data I/O • Information Technology – Hardware & software used by the information processes

  9. Example of a System • Braking system of a car • The Purpose is to slow the car down • Braking system requires resources or components such as brake pads, break disks, brake pedal • Components work together to process/make the car slow down • The Environment is everything that is influenced by the system

  10. Diagrammatic Representation of a System Environment – The Car, Including all its various sub-system System – The Braking System Purpose – To slow down the car Processes – Pressing brake pedal, fluid moving to callipers, friction between pads and disk, wheel slowing down, etc Resources – Brake pedal, master cylinder, callipers, brake pads and disks, wheels tyres, etc

  11. Example of a Information System in Context (ISC)

  12. Pool Filtration System • A backyard swimming pool contains a filtration system that includes a timer, a pump, a filter, various pipes and electrical connections and a skimmer box. These components work together to keep the pool water clean and healthy. Fig 2.2 shows many of these components, together with the flow of water. Figure 2.2
