The Research Of Public Logistics Information System Platforms

The logistics plays more important role in development of modern economy, Logistics information system can enhance operating efficiency, lower the logistics cost and speed ability of reaction .it provides value-added service for customer.The information level of logistics management and operating has become one of important markers of distinguishing modern logistics from traditional logistics.The public logistics information platforms can integrate various information resources. Realize the data exchange among the systems and information share.The logistics platforms integrates various system such as business enterprise, owner of goods, highway, railroad, port, bank, maritime customs, the industry and business tax etc. The information among the above systems can be exchanged and transferred by using the plateform,it can satisfy the needs of different customers and enhance the efficiency of logistics system.With the continuous development of computer science and technology, the application systems in the future will be multilayer ones based on the object oriented, distributed, isomerous conditions. This kind of system is composed of distributed objects one by one, which have given functions singly. These objects are independent of network protocols, programming languages, and software and hardware platforms. These pro- perties make them communicate each other and work corporately.The distributed component technology is used to deal with the large- scale programming development. The development based on component is the mainstream technology of desktop system now.The distributed Web technology is a combination of network and database technologies and it is also an application of multilayer distributed application.Currently, Web development application just to the direction development of the distributed framework, the distributed applications shielded the system in the existent and different framework , providing the distributed object with each other operability. The distribute object technique has already become the core technique that builds up the service application frame and software component.The main works of this dissertation are:(1) Giving the system structure and total structure of the public logistics information system platforms.(2) Introducing and analyzed the main function of the public logistics information system platforms and in actualize method;(3) applying the technique to carry on elaborate according to the Internet distributed the network database, and give to the method of the distribute database search.(4) Analyzed the distributed object technique and the component techn- iques, and combine multilayer framework, the point analyzed according to the distribute object technical two kinds of essential technique routes:Technique of COM/ DCOM, technique of CORBA.(5 ) Research to the XML applied method.
