Different Types of Information Systems Alexis Chua SYANDES K31

  1. 1. Prepared by : Alexis Sheena D. Chua SYANDES K31
  2. 2. TRANSACTION PROCESSING SYSTEM It is an information processing system for business transactions involving business transactions involving the collection, modification , and retrieval of all transaction data. It is also known as transaction processing or real-time processing.
  3. 3. Where it is being used? Businesses such as IT merchant services or other parts of the software architecture. It is a model for various transactions, including both financial transactions and other processes like verifications. It provides data for other business processes like management information system/ decision support system and special purpose information systems. It can also be used to capture and process data that describes fundamental business transactions, update databases and to produce a variety of reports.
  4. 4. Examples of systems that fall into Transaction Processing System IBM Transaction Processing Facility ( TPF) IBM Information Management System (IMS) IBM Customer Information Control System ( CICS) UNIVAC Transaction Interface Package (TIP)
  5. 5. Office Automation System (OAS) Office Automation System refers to the varied computer machinery and software used to digitally create, collect, store, manipulate, and relay office information needed to accomplishing basic tasks. Raw data storage, electronic transfer, and the management of electronic business information comprise the basic activities of an OAS. It also helps in optimizing or automating existing office procedures.
  6. 6. Where does OAS being used? The conversion of information to electronic form The backbone is a LAN, which connects users to transmit data, mail, and even voice across the network. Its advantages are the following: Office automation can get many tasks accomplished faster. It eliminates the need for a large stuff. Less storage is required to store data. Multiple people can update data simultaneously in the event of changes in schedule.
  7. 7. Systems that fall into OAS Document Management Systems Message Handling Systems Teleconferencing Systems
  8. 8. Knowledge Work Systems( KWS) KWS serves the information needs at the knowledge level of the organization. It is the process of capturing, developing, sharing, and effectively using organizational knowledge. It refers to a multi-disciplined approach to achieving organizational objectives by making the best use of knowledge.
  9. 9. Where it is being used? It can be used by people who hold formal university degrees and who are often members of a recognized profession such as lawyers, engineers, doctors, and science. Their job consists primarily of creating new information and knowledge. KWS, such as scientific or engineering design workstations, promote the creation of new knowledge and technical expertise are properly integrated into the business.
  10. 10. Examples of systems that fall into KWS Computer - aided Design (CAD) Computer aided Manufacturing (CAM) Virtual reality systems Virtual Reality Modelling Language (VRML) Investment workstations Computer Design System
  11. 11. Decision Support System (DSS) A Decision Support System (DSS) is a computer based information system that supports business or organizational decision-making activities. It can either be computerized, human, or a combination of both.
  12. 12. Where it is being used? DSS serves the management, operations, and planning levels of an organization and help to make decisions, which may be rapidly changing and not easily specified in advance. DSS applications are not single information resources, such as a database or a program that graphically represents sales figures, but the combination of integrated resources working together.
  13. 13. Examples of systems that fall under DSS File Drawer systems Suggestion systems Optimization systems Representational models Accounting models Analysis information systems Data Analysis Systems University of Vermont PROMIS system (for medical decision making)
  14. 14. Executive Support System (ESS) An Executive Support System (ESS) is a software that allows users to transform enterprise data into quickly accessible and executive- level reports, such as those used by billing , accounting, and staffing departments . It is also known as Executive Information System ( EIS). It is commonly considered a specialized form of decision support systems.
  15. 15. Where it is being used? It enhances decision making for executives. Used by billing, accounting, and staffing departments. It facilitates and supports senior executive information and decision-making needs. It provides easy access to internal and external information relevant to organizational goals.
  16. 16. Examples of systems that fall under ESS Corporate Management Technical Information Dissemination Cambridge Systematic
  17. 17. Group Decision Support Systems (GDSS) Group-Decision Support Systems (GDSS) are a class of electronic meeting systems, a collaboration technology designed to support meetings and group works. It is also categorized within a time-place paradigm.
  18. 18. Where is GDSS being used? It is designed to support meetings and group works. It is more focused on task support. It has come to mean computer software and hardware used to support group functions and processes. “High –level managers can spend 80% of their time making decisions on groups, thus, GDSS can reduce this time, arriving at a better decision faster.” It provides the hardware, software, databases, and procedures for effective decision making.
  19. 19. Types of GDSS Suggestion model File Drawer system Group Decision Room
