Chapter 1: "Information Systems: The Big Picture"— • This chapter helps you understand what information systems are and how they have become a vital part of modern organizations. We walk the student through the technology, people, and organizational components of an information system, and we lay out types of jobs and career opportunities in information systems and in related fields. We use a number of cases and examples, such as that of Ticketmaster, to show the student the types of systems being used and to point out common "best practices" in systems use and management.
Chapter 2: "Information Systems for Competitive Advantage"— • In this chapter we talk about Microsoft's use of information systems to support the Xbox product, along with other business examples, to show how to use information systems to support organizational strategy and enable competitive advantage. We also show the student how to formulate and present the business case for a system, and we explain why and how companies are continually looking for new ways to use technology for competitive advantage.
Chapter 3: "Database Management“— • Databases have become the engine running underneath all information systems and business processes. In this chapter, we use the examples of the Hard Rock Cafe and other businesses to describe what databases and database management systems are and to show why they have become very important for successful, modern organizations.
Chapter 4: "Telecommunications and the Internet"— • Just as databases are the underlying engines, telecommunications and networks are the veins through which vital information flows in organizations. Here we use examples from Pepsi and other companies to show you how people use telecommunications and networking equipment effectively. We also focus on how the Internet and the World Wide Web function and are used heavily by business organizations today.
Chapter 5: "Electronic Commerce, Intranets, and Extranets"— • Perhaps nothing has changed the landscape of business more than the use of the Internet for electronic commerce. In this chapter, we describe how a number of firms, such as Amazon, are using the Internet and Web to do business with customers, building intranets to support internal processes, and building extranets to interact with other firms.
Chapter 6: "Organizational Information Systems"— • Given how many different types of information systems organizations use, in this chapter we use examples from J.Crew and other firms to describe the various types of systems. We provide ways to categorize the systems so that you can better make sense of them all.
Chapter 7: "Enterprise-Wide Information Systems"— • In this chapter we focus on enterprise systems, which are a popular type of information system used to integrate information and span organizations' boundaries to better connect a firm with customers, suppliers, and other partners. We show you how John I. Haas, a global producer of fine hops for beer making, and other firms use Enterprise Resource Planning, Customer Relationship Management, and other popular types of software packages to compete.
Chapter 8: "Information Systems Development and Acquisition"— • How are all these systems built? In this chapter we show you how Tower Records and other firms build and acquire new information systems. We walk you through the traditional systems development approach, as well as more contemporary approaches such as prototyping, rapid application development, and object-oriented analysis and design.
Chapter 9: "Information Systems Ethics, Computer Crime, and Security"— • In this chapter we describe the ethical dilemmas associated with information systems, as well as common forms of computer crime and various methods for providing computer security. We show you how Microsoft and other firms deal with hackers and ensure the safety and integrity of their critical systems.
In addition to these nine chapters, we include three appendixes focusing on • basic hardware, • software, • and networking concepts.
