  • 1. Information Systems Concepts and Trends
  • 2. Structure Of MIS   1. 2. Structure of MIS is a difficult concept to understand because there is no standard or universally accepted framework for describing MIS. MIS structure may be described by following a variety of different approaches: Physical Components. Decision Support.
  • 3. MIS Structure Based on Physical Components  Hardware : Hardware refers to the physical data processing equipment and peripheral devices. For Eg.CPU, monitor, keyboard, printer, drives, tapes, communication devices, etc.  Software : Software is the board term given to the instructions or programs that direct the operation of the hardware. Software could be of two types, i.e. system software and application software.
  • 4. MIS Structure Based on Physical Components, Cont.  Database : The database consist of all data utilized by application software. Data is stored in files.  Procedures : Formal operating procedures, which are required to operate a system, such as manuals, are also regarded as physical elements.
  • 5. MIS Structure Based on Physical Components, Cont.  Operating Personnel : Personnel like Computer Operators, Computer Programmers, System Analysts, System Managers, etc., are the operating people of the information systems.
  • 6. Decision Support    Structure of MIS can also be described on the basis of its support in decision-making in an organisation.Desicion vary with respect to the structure that can be provided for making them. A highly structured decision can be pre-planned, whereas a highly unstructured decision cannot. A structured decision, because of its well-defined nature can be said to be programmable. However, it should not be taken to necessarily mean that the decision is automated,although many programmable decisions are automated.
  • 7. Decision Support,cont.  The structured, programmable decision tends to be routine and frequently repeated, the unstructured decision tends to occur with less frequency and tends to be irregular.  Information system support will fit easily into this classification, but some decisions are more or less structured and have some elements that are programmable and some that are not. Such decisions are semistructured decisions.
