物流信息系统体系结构

Architecture Design of Logistics Information System

论述了以航运为主业的大型物流信息系统体系结构的设计课题 ,包括物流业务的层次结构 ,网络体系结构 ,数据分布结构 ,应用系统计算结构和物理体系结构等 .在本文提出的体系结构设计方案中 ,为了与业务的组织功能结构相适应 ,采用了集中分布式的网络体系结构和数据分布结构 .为了减轻系统维护与升级的成本与工作量 ,应用系统采用了B/S计算结构 .最后 ,为了便于系统处理能力的扩充 ,采用了多层服务器结构 ;并适当采用冗余技术和群集技术 ,以满足高可靠性和安全性 .

This paper discusses some topics about architecture design of logistics information system, including the level structure of logistics business, the structure of enterprise network, the distributed data architecture, the application computing architecture and the physical architecture of the headquarter. In the design the central distributed network and data architecture are adopted to match the business architecture; the B/S application computing architecture is used to reduce the cost of maintenance and updating of systems and the N tier server architecture is used for the headquarter to achieve high availability and security.
