The Research On MIS Of Logistics Based On XML And Distrbuted Technology

Nowadays, modern logistics, which is regarded as the third source of profit, is flourishing with the tendency of economic globalization and revolution of information technology. With the establishment of socialist marketing economy, quick progress of global economy incorporation and rapid development of science technology, logistics industry, a rising industry, will turn into a new domain of increasing economy in China this century. The specialization and socialization of logistics service is an embodiment of social work dividing, the development of which will certainly be a driving force for improving China's economy.With the quick development of logistics industry, logistics enterprises, especially the third-party logistics(3PL), need more data exchange. Building efficient, steady, easy maintaining and extensible information systems is needed by the development of logistics industry. The automatic exchange of information in logistics industry is an important factor that restricts the quick development of the industry. In addition, current two-tier Client /Server information systems cannot meet the need of modern logistics industry's development.This paper mainly studies on two problems above, and introduces technologies in building logistics information systems, which mainly include XML and N-tier distributed systems. The main content includes the following two aspects: 1) N-tier structure is studied thoroughly and systematically, and different N-tier structures in various period of history are analyzed. Considering management, maintenance and efficiency, this paper suggests the enterprises to adopt three-tier Client/Server or Browser/Server systems, 2) the content of XML and its characteristics are introduced in detail, and the application of XML in data exchange is studied. In the end, this paper presents a model of XML data exchange in N-tier distributed systems.
