Equipping you with a solid understanding of the core principles of IS and how it is practiced, the brief FUNDAMENTALS OF INFORMATION SYSTEMS, 8E covers the latest developments from the field and their impact on the rapidly changing role of today's IS professional. A concise nine chapters, this streamlined book includes expansive coverage of mobile solutions, energy and environmental concerns, cloud computing, IS careers, virtual communities, global IS work solutions, and social networking. You learn firsthand how information systems can increase profits and reduce costs as you explore new information on e-commerce and enterprise systems, artificial intelligence, virtual reality, green computing, and other issues reshaping the industry. The book also introduces the challenges and risks of computer crimes, hacking, and cyberterrorism. A long-running example illustrates how technology was used in the design, development, and production of this book. No matter where your career path may lead, FUNDAMENTALS OF INFORMATION SYSTEMS, 8E can help you maximize your success as an employee, a decision maker, and a business leader.
The real threat to information system security comes from people, not computers. That's why students need to understand both the technical implementation of security controls, as well as the softer human behavioral and managerial factors that contribute to the theft and sabotage proprietary data. Addressing both the technical and human side of IS security, Dhillon's Princliples of Information Systems Security: Texts and Cases equips managers (and those training to be managers) with an understanding of a broad range issues related to information system security management, and specific tools and techniques to support this managerial orientation. Coverage goes well beyond the technical aspects of information system security to address formal controls (the rules and procedures that need to be established for bringing about success of technical controls), as well as informal controls that deal with the normative structures that exist within organizations.
Whether it's because of a lack of understanding, poor planning, or a myriad of other things, 50 to 60 percent of the IT effort in most companies can be considered waste. Explaining how to introduce Lean principles to your IT functions to reduce and even eliminate this waste, Lean Management Principles for Information Technology provides t
Principles of Computer System Design is the first textbook to take a principles-based approach to the computer system design. It identifies, examines, and illustrates fundamental concepts in computer system design that are common across operating systems, networks, database systems, distributed systems, programming languages, software engineering, security, fault tolerance, and architecture.Through carefully analyzed case studies from each of these disciplines, it demonstrates how to apply these concepts to tackle practical system design problems. To support the focus on design, the text identifies and explains abstractions that have proven successful in practice such as remote procedure call, client/service organization, file systems, data integrity, consistency, and authenticated messages. Most computer systems are built using a handful of such abstractions. The text describes how these abstractions are implemented, demonstrates how they are used in different systems, and prepares the reader to apply them in future designs.The book is recommended for junior and senior undergraduate students in Operating Systems, Distributed Systems, Distributed Operating Systems and/or Computer Systems Design courses; and professional computer systems designers. - Concepts of computer system design guided by fundamental principles - Cross-cutting approach that identifies abstractions common to networking, operating systems, transaction systems, distributed systems, architecture, and software engineering - Case studies that make the abstractions real: naming (DNS and the URL); file systems (the UNIX file system); clients and services (NFS); virtualization (virtual machines); scheduling (disk arms); security (TLS) - Numerous pseudocode fragments that provide concrete examples of abstract concepts - Extensive support. The authors and MIT OpenCourseWare provide on-line, free of charge, open educational resources, including additional chapters, course syllabi, board layouts and slides, lecture videos, and an archive of lecture schedules, class assignments, and design projects
The late 20th century has witnessed increasing crises in the world's marine fisheries. A causal analysis of these reveals that a common element are various manifestations of spatial inequity. This most frequently includes the inequity of access rights to the resource, but factors such as variations in resource depletion, spatio-temporal variations in stock recruitment, the imposition of regulatory zoning, destruction of marine ecosystems and the siting of mariculture facilities are other examples. To resolve some of these problems, management practices must be improved. As has been shown in other fields where spatially related problems occur, there is now a promising tool, Geographical Information Systems (GIS), which, combined with other analytical tools and models, could allow for improved spatial management. GIS are basically integrated computer based systems which allow for the input of digital geo-referenced data to produce maps plus other textual, graphical and tabular output. The essential usefulness of GIS however, lies in its ability to manipulate data in a large number of ways and to perform various analytical functions so as to produce output which makes for more efficient decision making.As with many computer based systems, the key to GIS success lies in the acquisition of suitable data. The various means by which both primary and secondary data can be located, gathered, accessed and stored are described.
Managing & Using Information Systems: A Strategic Approach provides a solid knowledgebase of basic concepts to help readers become informed, competent participants in Information Systems (IS) decisions. Written for MBA students and general business managers alike, the text explains the fundamental principles and practices required to use and manage information, and illustrates how information systems can create, or obstruct, opportunities within various organizations. This revised and updated seventh edition discusses the business and design processes relevant to IS, and presents a basic framework to connect business strategy, IS strategy, and organizational strategy. Readers are guided through each essential aspect of information Systems, including information architecture and infrastructure, IT security, the business of Information Technology, IS sourcing, project management, business analytics, and relevant IS governance and ethical issues. Detailed chapters contain mini cases, full-length case studies, discussion topics, review questions, supplemental reading links, and a set of managerial concerns related to the topic.
