Understanding information systems : what they do and why we need them /

With the emergence of the Information Society, it behooves even nonexperts to gain some familiarity with the commodity that is rapidly transforming their lives. In this vein, Ratzan (Univ. of Medicine and Dentistry of New Jersey) has written a general introduction to information systems; coverage is thorough and his organization impeccably logical. In chapter 1 he defines his topic and in succeeding chapters methodically explains the processing of information (including representing, organizing, retrieving, networking, securing, concealing, measuring, counting, numbering, and managing). Many chapters conclude with exercises and research questions that are creative, thought-provoking, and current. On the other hand, Ratzan has taken on the Herculean task of trying to pitch his book to an audience of such scope that it ranges on one extreme to the general public and humanities students and on the other to computer science students. He has not been entirely successful. His unremitting barrage of definitions of basic terms, for example, will be vertiginous for the humanities student and soporific for the computer science student. Perhaps conceding the dry nature of his subject matter, he also attempts to effect a humorous tone. This humor is no more than a mild palliative, though, for Ratzan's relentlessly monolithic style. ^BSumming Up: Recommended. All levels. D. M. Gilbert Maine Maritime Academy

Unlike most books discussing information systems, this one is not oriented to a specific application, time, or technology. Instead, readers are treated to 16 chapters covering different aspects of information, among them description, representation, organization, retrieval, networking, security, concealment, measurement, and management of information. The computer, Internet, and music are also discussed in terms of information systems. Information is well articulated, insightful, and strengthened by illustrative exercises and helpful appendixes. The author's use of humor is a welcome addition, making the text more engaging and palatable. Although conceived for the general reader, this resource would most likely appeal to students and instructors in library and information studies or computer science. Mathphobic readers or those uncomfortable with quantitative data may find the text a bit daunting at times, but for those willing to make the effort, the rewards are great and plentiful. -- RBB Copyright 2004 Booklist
