Matching client/server processing architectures with information processing requirements: A contingency study

INFORMATION & MANAGEMENT 1998年第5期34卷 265-274页

作者： Anandarajan, M Arinze, B Drexel Univ Dept Management Philadelphia PA 19104 USA

The 1990s are witnessing the rapid growth of client/server (C/S) computing, but for an organization to benefit from a CIS model, it should ensure that the processing architecture matches its information needs. Researchers have suggested that organizations moving to this model should identify their information requirements, and then determine the appropriate architectures to support them. This study utilizes information processing theory to examine the match between an organization's information processing requirements and its C/S architectures. The independent variables in this study are task characteristics, and the processing architectures. The dependent variable is effectiveness. The data for this study was obtained from C/S managers and users in a variety of industries, through a combination of archival data, telephone interviews, and a mailed survey. It was analyzed using hierarchical regression. The results indicate that an appropriate match between task characteristics and C/S processing architectures is an important determinant of system effectiveness.

COMPUTER 1999年第5期32卷 112-+页

作者： Vetter, R Univ N Carolina Dept Comp Sci Wilmington NC 28403 USA

The paper considers how Web technologies have emerged as a credible alternative to client-server computing in the corporate enterprise. Web-based enterprise computing allows corporate IT to integrate disparate systems into a single, coherent environment. This shift from a traditional Web server with database connectivity to integrated systems that support the use of Web technologies facilitates business processes and allows corporations to service both internal and external customers effectively

Distributed speech processing in MiPad's multimodal user interface

引用

IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 2002年第8期10卷 605-619页

This paper describes the main components of MiPad (Multimodal Interactive PAD) and especially its distributed speech processing aspects. MiPad is a wireless mobile PDA prototype that enables users to accomplish many common tasks using a multi-modal spoken language interface and wireless-data technologies. It fully integrates continuous speech recognition and spoken language understanding, and provides a novel solution for data entry in PDAs or smart phones, often done by pecking with tiny styluses or typing on minuscule keyboards. Our user study indicates that the throughput of MiPad is significantly superior to that of the existing pen-based PDA interface. Acoustic modeling and noise robustness in distributed speech recognition are key components in MiPad's design and implementation. In a typical scenario, the user speaks to the device at a distance so that he or she can see the screen. The built-in microphone thus picks up a lot of background noise, which requires MiPad be noise robust. For complex tasks, such as dictating e-mails, resource limitations demand the use of a client-server. (peer-to-peer) architecture, where the PDA performs primitive feature extraction, feature quantization, and error protection, while the transmitted features to the server are subject to further speech feature enhancement, speech decoding and understanding before a dialog is carried out and actions rendered. Noise robustness can be achieved at the client, at the server or both. Various speech processing aspects of this type of distributed computation as related to MiPad's potential deployment are presented in this paper. Recent user interface study results are also described. Finally, we point out future research directions as related to several key MiPad functionalities.

End-to-end latency of a fault-tolerant CORBA infrastructure

引用

PERFORMANCE EVALUATION 2006年第4-5期63卷 341-363页

作者： Zhao, W Moser, LE Melliar-Smith, PM Univ Calif Santa Barbara Dept Elect & Comp Engn Santa Barbara CA 93106 USA

This paper presents an evaluation of the end-to-end latency of a fault-tolerant CORBA infrastructure that we have implemented. The fault-tolerant infrastructure replicates the server applications using active, passive and semi-active replication, and maintains strong replica consistency of the server replicas. By analyses and by measurements of the running fault-tolerant infrastructure, we characterize the end-to-end latency under fault-free conditions. The main determining factor of the run-time performance of the fault-tolerant infrastructure is the Totem group communication protocol, which contributes to the end-to-end latency primarily in two ways: the delay in sending messages and the processing cost of the rotating token. To reduce the delay in sending messages for passive and semi-active replication, the position of the primary server replica on the Totem ring, the token rotation time, the processing time at the client, and the processing time at the server must be considered. For active replication, the presence of duplicate messages adversely affects the performance. However, if an effective sending-side duplicate suppression mechanism is implemented, active replication is more advantageous than both passive and semi-active replication because of the automatic selection of the most favorable position of the server replica that sends the first non-duplicate reply.

Classifies the critical knowledge/ skill set according to content or domain of knowledge by means of a survey. This is conducted in accordance with what IS practitioners and educators can easily relate. The survey uses this approach and includes four broad categories of critical Information Systems (IS) knowledge/skills: IS technology knowledge/skills, organizational and societal knowledge/skills, interpersonal knowledge/skills, and personal trait knowledge/skills.

Design of an Integrated Project Management Information System for Large Scale Public Projects: Iranian Case Study

引用

JOURNAL OF INFORMATION TECHNOLOGY RESEARCH 2011年第3期4卷 14-28页

作者： Taghavi, Mona Patel, Ahmed Taghavi, Hamed Univ Kebangsaan Malaysia Management Informat Syst & Network Secur Bangi Malaysia Univ Kebangsaan Malaysia Bangi Malaysia Kingston Univ Kingston Upon Thames Surrey England Iranian Strateg Informat Solut Co ISISCO Tehran Iran

Due to the unprecedented growth of outsourcing ICT projects by the Iranian government, a critical need exists for the proper execution and monitoring of these projects. In this paper, the authors propose a web-based project management system to improve the efficiency and effectiveness of the management processes and accelerate decision making. Based on the requirements and information flow between various units involved in the complete life-cycle of ICT project management, a functional model and system architecture with various underlying structures has been designed. The functional model contains two sub-systems: process management and information service. The proposed system structure is based on a four-layer client-server computing model. As a part of a publically available ICT system, it must be secure against cybercrime activities. This system can bring efficiency in managing the projects, improve decision making, and increase the overall management process with total accounting and management transparency. The proposed system overcomes the problems associated with a central system and traditional management processes, as is currently the case in Iran.
