A Framework for Information System Architecture

Information systems engineering professionals perform the invaluable function of aiding knowledge workers in a variety of judgment and choice activities. Those who use decision support systems are involved in an important number of day-to-day activities— from the design of aircraft flight control systems to management systems that enable better financial decisions. Decision support designers and users should function together to insure the development of appropriate information systems. Decision Support Systems Engineering describes how to establish a decision support system that unites the concerns of both system designers and users. Beginning with an outline of the generic components of a decision support system, readers are given a technologically rigorous, yet clear, tour of its assembly line basics. Data-base management systems, model-base management systems, and dialog generation and management systems are clearly described, with emphasis on how these make a decision support system feasible and practical. Using the framework of a total life cycle systems management process, the book describes approaches for developing appropriate integrated information systems architectures— approaches that take into account user needs and the translation of user needs into system requirements. Hardware and software allocations of these requirements and the subsequent development of suitable hardware and software architectures are methodically detailed. Also considered in-depth is the subject of cognitive systems engineering, which recognizes and seeks to ameliorate inherent potential flaws in human information processing. Presented here are ways in which decision support systems can beused to avoid cognitive information-processing biases and errors.

Traditional software engineering approaches to managing innovation, productivity, and quality assurance focus almost entirely on the performance of individual programmers. But, just as those working in the environmental sphere have come to realize the dangers of focusing too narrowly on individual species while ignoring the needs of overall ecosystems, thinkers in the field of information systems engineering have begun to recognize the need for a systems management approach that encompasses all facets of the software development organization. Now, this groundbreaking text offers such an approach. In it, Professor Andrew Sage provides readers with a rational framework for the production of trustworthy, high-quality software and information technology systems. These combine cutting-edge systems engineering methodologies developed at top software development firms with innovative process management approaches that have been introduced successfully by many of the leading information technology and other business organizations around the world over the past decade. The bottom line of the systems management approach outlined is total quality assurance through process-related improvements throughout the entire organization. The book, therefore, addresses, in depth, a wide array of interrelated issues, many of which are not generally covered in systems engineering texts, including: process development life cycle; process configuration management; systems architectures and integration; product development standards; metrics for cost and operational effectiveness evaluation; evaluation and reengineering of organizational cultures; strategic quality assurance and management, or TQM; and processreengineering and maturity.

Software architecture - Software architecture or software systems architecture can best be thought of as a representation of an engineered (or To Be Engineered) software system, and the process and discipline for effectively implementing the design(s) for such a system. Such a software system is generally part of a larger system encompassing information and general and/or special purpose computer hardware.

Flask operating system - The Flask operating system architecture is a joint venture between the National Security Agency, the University of Utah, and the Secure Computing Corporation project designed to provide a framework for a more secure operating system. Development and implementation started with the Mach microkernel, and has since shifted its focus to the Linux operating system, and is now better known as Security-Enhanced Linux (or SE Linux).

Hospital information system - A hospital information system (HIS) is a comprehensive, integrated information system designed to manage the administrative and clinical aspects of a hospital. This encompasses paper-based information processing as well as data processing machines.

Geographic information system - A geographic information system (GIS) is a system for creating and managing spatial data and associated attributes. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, and displaying geographically-referenced information.
