Recently, with the development of Manager Information System and the arrival of E-business times, The Technique of communication have reached anywhere of the world. In addition to the large-scale development of the Circulating Operation, The high development of Circulating Industry and Production System has made the logistics industry a great improvement. And all these factors make logistics is not only a kind of campaign, it must, adapt to the development of global manufacturing industry and the maximum complication of the Society manufacture. It need logistics have more perfect adaptable development. Thus respond to the age-request, Modern logistics should be combined with the technique of network, information and computer etc. In this paper, the Developing Tendency of the logistics is systemic analyzed; CSCW and technique of Distributed Database is general described; besides, combined with topic, bring the approach to the problem in database design.Now, With the development of society and the advancement of Science and Technology, all kinds of jobs become more and more complex. So CSCW is increasingly important. The goal of research is to use computer and communication technique to overcome spatial and temporal obstacles of group work. Consequently, work efficiency is enhanced. In this paper the three factors of CSCW: communication, cooperation and harmony; Classifying of CSCW system is introduced. The main problems of CSCW system are analyzed in detail.Distributed database is the production that was combined by the computer network and database technology. It has a many years history in database domain. It has its own two specialties: distributing of data; reconciliation of data. In distributed database system, it is not the centralized control of system but the site autonomy is emphasized. And the system should keep the data distributed, and then, the instance of data' s distributing can be ignored when program the application. The paper defines the concept of Distributed Database, the characteristics and structure of the Distributed Database System, the design rule and step of the Distributed Database, etc. Also the paper describes the materialization of Distributed Database on the configuration of Logistics System. Combined with the topic, adopt the logistics system as the archetype system, design the distributed database of the system: the E-R chart, selecting of data storage mechanism, Accessing mode of the distributed database is given in the paper. And then describe distributed Transaction Process and distributed query, etc. besides, Deadlock Detection Algorithms in distributed database is deeplyanalyzed.With ASP. NET as fore-end develop environment, SQL Server 2000 as database management tool on the background, Use B/S mode offer the users flexibility and friendly interface. And then, realize all modules of the logistics system.
