  1. BIS2180 Information Technology Enterprise Computing

  2. Objectives Overview

  3. What Is Enterprise Computing? • Enterprise computinginvolves the use of computers in networks, such as LANs and WANs, or a series of interconnected networks that encompass a variety of different operating systems, protocols, and network architectures

  4. What Is Enterprise Computing? • Types of enterprises include:

  5. What Is Enterprise Computing? • Most traditional enterprises are organized in a hierarchical manner

  6. What Is Enterprise Computing? • In an enterprise, users typically fall into one of four categories:

  7. What Is Enterprise Computing? • Enterprise informationis the information gathered in the ongoing operations of an enterprise-sized organization • Business intelligence • Business process management • Business process automation

  8. Information Systems in the Enterprise • An information systemis a set of hardware, software, data, people, and procedures that work together to produce information

  9. Information Systems in the Enterprise Page 491 Table 11-3 Discovering Computers 2014: Chapter 11

  10. Information Systems in the Enterprise • Functional units within an enterprise might include:

  11. Information Systems in the Enterprise • Accounting software manages everyday transactions • Billing software helps the company reconcile purchases with customer payments • Financial software helps managers budget, forecast, and analyze

  12. Information Systems in the Enterprise • A human resources information system(HRIS) manages one or more human resources functions • Employee relationship management systems manage communication between employees and the business

  13. Information Systems in the Enterprise • Computer-aided design(CAD) uses a computer and special software to aid in engineering, drafting, and design • Computer-aided engineering(CAE) uses computers to test product designs

  14. Information Systems in the Enterprise • Computer-aided manufacturing (CAM) is the use of computers to control production equipment • Computer-integrated manufacturing(CIM) uses computers to integrate the many different operations of the manufacturing process

  15. Information Systems in the Enterprise

  16. Information Systems in the Enterprise

  17. Information Systems in the Enterprise • Sales force automation (SFA) software equips traveling salespeople with the electronic tools they need to be more productive

  18. Information Systems in the Enterprise • Distribution systems perform the following functions:

  19. Information Systems in the Enterprise • Customer interaction management(CIM) software manages the day-to-day interactions with customers

  20. Information Systems in the Enterprise • The information technology (IT) department makes technology decisions for the enterprise • Whether to build or buy new information systems • When a computer or information system has outlived its useful life • Web site management programs collect data designed to help organizations make informed decisions regarding their Web presence

  21. Information Systems in the Enterprise • General purpose information systems generally fall into one of five categories

  22. Information Systems in the Enterprise • Batch processing vs. online transaction processing

  23. Information Systems in the Enterprise • A management information system (MIS) is an informationsystem that generates accurate, timely, and organized information, so that managers and other users can make decisions, solve problems, supervise activities, and track progress

  24. Information Systems in the Enterprise • A decision support system (DSS) helps users analyze information and make decisions

  25. Information Systems in the Enterprise • An expert system is an information system that captures and stores the knowledge of human experts and then imitates human reasoning and decision making

  26. Information Systems in the Enterprise

  27. Information Systems in the Enterprise

  28. Enterprise-Wide Technologies and Methodologies • Some technologies used in enterprises include:

  29. Virtualization and Grid Computing • Virtualization is the practice of sharing or pooling computing resources

  30. Virtualization and GridComputing Grid computingcombines many servers and/or personal computers on a network to act as one large computer

  31. High Availability, Scalability, and Interoperability • A high-availability systemcontinues running and performing tasks for at least 99 percent of the time • May include hot-swappingandredundant components • When a component fails, anothercomponent takes over and thesystem continues to function

  32. High Availability, Scalability, and Interoperability • Scalability is a measure of how well computer hardware, software, or an information system can grow to meet increasing performance demands • Interoperability is the ability for an information system to share information with other information systems within an enterprise
