| Enterprise data exchange is like the artery of enterprise information systems. Efficient enterprise data exchange is the base of improving business efficiency, reducing operating costs and increasing the competitiveness of enterprises. With data exchange platform playing an important role in enterprise application integration, an enterprise needs an open data exchange platform for the integration of enterprise applications. This paper proposed a data exchange platform named ExistABC, which is oriented Electronic Government Administration. In the system, the unit of processing isomerous data is developed based on components.Software Components technology is the latest and cogent solution to reduce the time of software development, reduce maintenance costs and upgrade procedures dynamic. On the basis of discussing of relevant concepts of the components technology, the paper researches and analysis of the current epidemic of several main components models: Microsoft COM/DCOM/COM+, the OMG CORBA, EJB and Java Bean, discusses simply in the operating principles and structural framework. After a comparison, summers up the linkages and distinction between them. Then discusses component technology and software development based on the components.Through the description of the whole technical structure of ExistABC system and components throughout the system, the analysis of the status and role of components in the system and the analysis of demand of components, this paper gives an EAC components model. The model supports visualization components assembly. Then it is given a detailed e exposition and analysis.At last, the paper applies the EAC components model to ExistABC system. Then it makes a division of the system based on components, and realizes components development environment, the working environment and specific components. Then the primary function of the system is realized and feasibility and effectiveness of the EAC model components is validated. |
