Data quality in collaborative commerce
International Journal of Information Quality, 2011Co-Authors: Duanning Zhou, Kazuo Nakatani, Ta Tao ChuangAbstract:Collaborative commerce (c-commerce) is an information technology-enabled process for organisations to share data and resources, adjust their activities, and augment each other's capabilities in order to reap mutual benefits. Data quality has long been an important issue that may compromise the potential of information systems. Assuring data quality is more critical in c-commerce than it is in intra-organisational information systems because of the need for extensive sharing and exchange of data among business partners. In order to better understand and then measure and manage data quality in c-commerce, this study points out that inter-organisational data integration, inter-organisational data synchronisation, and inter-organisational data transparency are the major data quality issues in c-commerce, and proposes the different levels of data integration, data synchronisation, and data transparency. This study also discusses how to use two global information Networks in industry, Global Data Synchronization Network and the EPCglobal Network, to address the data quality issues in c-commerce.

DATA Synchronization TECHNOLOGY: STANDARDS, BUSINESS VALUES AND IMPLICATIONS
Communications of the Association for Information Systems, 2006Co-Authors: Kazuo Nakatani, Ta Tao Chuang, Duanning ZhouAbstract:The Internet-enabled connectivity has created opportunities for businesses to conduct various forms of collaborative activities. However, the findings of several surveys indicate that the deficiencies in data quality might compromise the potential benefits of joint efforts. Global data Synchronization (GDS), the process of timely updating product data to maintain the data consistency among business partners, is viewed as the key to materializing the benefits of ecollaboration in the global supply chain setting. In the paper, we present the need for data Synchronization, discuss the evolution of technical standards of data identification schemes, and introduce the Global Data Synchronization Network (GDSN), the platform on which global data Synchronization is substantiated. We detail the structure of GDSN and the protocols for the process of GDS. Furthermore, we discuss business and management implications of GDS, different approaches to implementing GDS, and challenges to the implementation of GDS. The emergence of GDS and GDSN presents research opportunities on issues relating to the implementation of GDS, the relationship between GDSN and EPCglobal Network, the impact of GDS on inter-organizational relationships, the Network effect of global standards, and evolution of complementary standards. We discuss these research opportunities. In brief, the article covers the history, present status, and future of GDS and GDSN, as well as their potentials, benefits, and implementation issues.

Feasibility Research on Integration of Power Frequency Synchronization Network With Time Synchronization Network
Power system technology, 2015Co-Authors: Teng LinAbstract:To meet the demands of power grid on time and frequency Synchronization performances and to change the present situation that the running of power time Synchronization is independent from that of power frequency Synchronization, the similarities of clock sources, node layout and Networking modes between power frequency Synchronization Network and power time Synchronization Network are analyzed and the feasible conditions of the integration of the two Networks are pointed out, and then a scheme of transmitting the time Synchronization signal by the 2M channel for power frequency Network is proposed, in which the PTP technique and E1/Ethernet protocol conversion technique are utilized. A PTP technique based clock skew algorithm, which transmits time Synchronization signal between master clock and slave clock, and the format conversion principle of PTP data packet via E1/Ethernet protocol converter are researched. During the format conversion the delay recording module is utilized to record the time difference for the protocol conversion to implement automatic delay compensation for conversion of E1 protocol and Ethernet protocol. Finally, Based on SDH Network a simulation platform for the integration of the frequency Synchronization Network with the time Synchronization Network is constructed, and the measurement results show that transmitting the time Synchronization signal by the integrated Network the time accuracy can reach the nanosecond precision, thus the demand of power business on time accuracy in the grade of microsecond can be satisfied, and it is also proved that the integration of the frequency Synchronization Network with the time Synchronization Network is feasible.
