  • 11. The Purpose of InformationSystemsWhy do people need Information? Individuals  Entertainment  Enlightenment Business  Decision making  Problem Solving  Control
  • 12. Data, Information andInformation SystemsDATA VS. INFORMATION data derived from the Latin datum, literally a given or a fact which might take the form of a number, a statement or a picture is the raw material in the production of information information  are facts or conclusions that have meaning within a contextNOTES: Raw data is rarely meaningful or useful as information To become information, data is manipulated through tabulation, statistical analysis, or any other operation
  • 13. Data, Information andInformation Systems con’tDATA MANIPULATIONGathering of data of the management of a car manufacturerfrom the customers Demographic data o Gender o Age o Annual income  Complaints about different performance areas  Features that satisfy buyers most  Courtesy of the dealer’s personnel
  • 14. Data, Information andInformation Systems con’tDATA MANIPULATION  Categorize complaints by topic  Total the number of complaints for each type of dissatisfaction and each car model  Calculate the average age and income of current buyers the company can now generate new information to improve marketing
  • 15. Data, Information and Information Systems con’tGENERATING INFORMATIONRaw data-processed in anIS to create finaluseful informationProcess-manipulation ofdataComputer-based IS’s-process data toproduce information
  • 16. Data, Information andInformation Systems con’tFor informationto be used, itmust be: Relevant Complete Accurate Current Cost efficient
  • 17. Data, Information andInformation Systems con’tWhat is a System? an array of components that work together to achieve a common goal, or multiple goals by accepting input, processing it, and producing output in an organized mannerSystems and Subsystems Subsystems  components of a larger system – with subgoals, all contributing to meeting the main goal  can receive input from, and transfer output to, other systems or subsystems
  • 18. Data, Information andInformation Systems con’tCLOSED VS. OPEN SYSTEMS Closed system  a system that stands alone, with no connection to another system: nothing flows in from another system, nothing flows out to another systemExample: a small check-producing system – prints and cuts checks whenan employee enters data through a keyboard Open System  a system that interfaces and interacts with other systemsExample: An accounting system that records accounts receivable,accounts payable, and cash flow is open if it receives its payroll figuresfrom the payroll system
