Networking high-end CAD systems based on PC/MS-DOS platforms

The concept of today\u27s technology has been dropped. Everything is now either oobsolete or experimental. Yesterday\u27s technology is appealing only because it is tried-and-true and prices are reduced for clearance. Tomorrow\u27s technology is exciting, somewhat expensive and not well tested. In the field of architecture, where most firms are medium or small, having limited resources, the high cost initially required for a CAD installation was generally impossible to meet not too many years ago. From spreadsheets and CAD graphics to network file systems and distributed database management, the basic systems and application tools have matured to the point that the possibilities are now limited mainly by how creatively the architects can apply them. CAD systems on the market today are not so different from the systems of the mid 70s, except they have gone from hardware costing a hundred thousand dollar to PC based systems, costing under ten thousand dollars. Choices of hardware and software for CAD systems undergo continual changes in power and efficiency. There will come a point where upgrading will create more a deficiency rather than an augmentation of capability efficiency and overall function. Thus it becomes a major problem for the prospect buyer

High Availability and Scalability of Mainframe Environments using System z and z/OS as example

Mainframe computers are the backbone of industrial and commercial computing, hosting the most relevant and critical data of businesses. One of the most important mainframe environments is IBM System z with the operating system z/OS. This book introduces mainframe technology of System z and z/OS with respect to high availability and scalability. It highlights their presence on different levels within the hardware and software stack to satisfy the needs for large IT organizations

A new model for the development of information systems

The most commonly used systems specification and design techniques in commercial computing are described and compared; Information Engineering as proposed by James Martin, A Framework for Information Definition-Muitiview proposed by Wood-Harper et al, Real-world Modeling as described by Jackson, Structured Analysis and Design as In Demarco, Yourdon and Constantine and Output-Oriented Structured Requirement Definition proposed by Orr. In addition, system prototyping is discussed, including the role of prototyping in large software development projects and as a tool for the design of human-computer interfaces. Other areas described and discussed include decision support systems (DSS) and knowledge based management support systems. The context is in the design and development approaches for DSS, prototyping for DSS, expert system for DSS and the integration of DSS and information system. The design and development of human-computer interface is also discussed in relation to user Interface complexity and adaptive interfaces. Further, the important issue of user involvement and support within the development process Is discussed. Thus, weaknesses of current approaches to the system development process are identified and a new model for the development of information system is proposed. In proposing the model, data and functional analysis structured method and methodology for decision support systems (DSS) development is presented including guidelines for the development of knowledge based DSS. The new proposed model is put to test in the design, development and implementation of large integrated commercial systems including DSS. Results and discussion on the use of the model is reported with special consideration to the users' and developers' view of the model. Finally the objectives of this research program are examined in relation to what has been achieved during this program of research. The prospect of using the model for the development of information systems are concluded with references to current and future goals

Steel: Nippon Steel, K.K.: Gaining and sustaining long-term advantage through information technology

This case for a large integrated steel producer, along with other cases, supports an initial research hypothesis that leading software users in the US and Japan are very sophisticated in the ways they have integrated software into their management strategies. They use it to institutionalize organizational strengths and capture tacit knowledge on an interactive basis. In Japan this strategy has involved heavy reliance on customized and semi-customized software (Rapp 1995) but is changing towards a more selective use of package software managed via customized systems. An example of this is Nippon Steel's development of an E-commerce system to automate its traditional faxed-based ordering system from the Japanese trading companies (TCs). In turn, US firms, such as Merck, who have often relied more on packaged software, are now customizing more. This is especially true for the systems needed to integrate software packages into something more closely linked with the firm's business strategies, markets, and organizational structure. Thus, coming from different directions, there appears to be some convergence in approach by these leading software users. These cases confirm what some other analysts have hypothesized; a coherent business strategy is a necessary condition for a successful information technology (IT) strategy (Wold and Shriver 1993. These strategic links for Nippon Steel and the Japanese steel industry are presented in the following case
