Data Processing: 1950s-1960s 2. Management Reporting: 1960s-1970s 3. Decision support: 1970s-1980s 4. Strategic and End User Support: 1980s-1990s 5. Global Internetworking: 1990s-2000s 9Data Processing: 1950s-1960s The first business application of computers (in the mid- 1950s) performed repetitive, high- volume, transaction-computing tasks. The computers "crunched numbers” summarizing and organizing transactions and data in the accounting, finance, and human resources areas. Such systems are generally called transaction processing systems (TPSs) 10Management Reporting: 1960s-1970s Management Information Systems (MISs): these systems access, organize, summarize and display information for supporting routine decision making in the functional areas. Office Automation Systems( OASs): such as word processing systems were developed to support office and clerical workers. 11Decision support: 1970s-1980s Decision Support Systems: were developed to provide computer based support for complex, non-routine decision. 12Strategic and End User Support: 1980s-1990s • The use or development of information systems by the principal users of the systems’ outputs, such as analysts, managers, and other professionals. • Intelligent Support System (ISSs): Include expert systems which provide the stored knowledge of experts to non-experts, and a new type of intelligent system with machine- learning capabilities that can learn from historical cases. • „ Knowledge Management Systems: Support the creating, gathering, organizing, integrating and disseminating of organizational knowledge. 13Global Internetworking: 1990s-2000s • „ Mobile Computing: Information systems that support employees who are working with customers or business partners outside the physical boundaries of their company; can be done over wire or wireless networks. 14Classification of IS Information Systems Operations Support Management Support System System Transaction Process Office Decision Executive Management processing automation support information information Control systems systems systems systems systems systems 151.
