Component-Based Distributed System Analysis and Design of EDI

This paper describes the background and development trends of EDI system, also gives an analysis of the existing EDI system which is summed up by the basic method and main functions, furthermore the existence of not unified operational standards, difficulty of integration, the inflexibility and poor- security of the used system and other outstanding issues are also discussed in the paper. The basic principles and ideas which are based on component technology and distributed processing technology are introduced to develop software. A set of components which are appropriate for distributed EDI System is designed. The components are assembled into a common distributed EDI system through component assembly technology. The paper has discussed the work process of distributed component-based EDI system and described the practical significance of the system and applications and prospects.
