Research On The Modeling Method And Application Of Information Resource Integration In E-government

In order to solve the problem of "Information Island" in the present construction of E-government, to make better use of information resource, to reduce redundancy, to realize information sharing, it is imperative to integrate the information resources. At present, the information resource integration of the academy is mainly concentrated on enterprise information resource and the library information resource, mostly conducting the research in details on aspect of software realization. Researches on modeling method and the realization of information resource integration are still the pioneering research tasks in the domains of E-government system design and software development, but lack corresponding instructing theories and methods.In such a situation, on the base of Professor Wang Yanzhang's E-R-P (Entity-Relation-Problem) Knowledge Expression Theory, facing the integration, this paper proposes a description model of information resource system. The information resource integration in E-government is regarded as system engineering, using the thought, theory and method of system science, conducting the researches on modeling method and the realization of information resource integration. Through the research of characteristics of information resource integration in the E-government and the fathoming, studying, practicing and the summarizing in the actual government information resource integration programs, the theoretical groundwork of E-R-P modeling system is modified and put into practice, conducting the system modeling and implementation of projects. The main research work of this paper is listed below:(1) Summarizing the situations of domestic and abroad developments of information resource integration and the correlative technologies, comparing the E-R-P modeling with the ER (Entity-Relation) model, the information resource integration with and the information resource plan. Analyzing the characteristics of the information integration in the domains of resource, information resource, government information resource and E-government from the viewpoint of system theory.(2) Expanding the theory of E-R-P knowledge expression system, proposing an E-R-P model facing the integration of information resource system description, which has entity, relation and problem as its basic elements. Giving advancedmathematic description of domain, entity, relation and problem, proposing the basic concept, mathematic description, formalization description, the forming method and the modeling process by introducing domain, atomic problem, meta-information, E-R-P matrix and the relevant contents, corresponding the E-R-P model with the object-oriented technology.(3) Combining the construction of E-R-P model, studying the modeling of government's information resource integration.(4) Proposing the E-R-P information management model in software system, guiding the instruction of the information resource integration platform.(5) Through the research of the information integration process, proposing the process model of the information resource integration. Discussing the general process of the information integration, giving the mathematic description and further study of the interactions in the integration process.(6) Participating in the software platform design of information resource integration system and the development of corresponding supporting tools. The software platform and the data exchange tool echo with the former integration modeling, co-serving the implementation of government information resource integration project. Finally applying the above modeling method and the system exploiter tool to the construct of "Fundamental Information Sharing of Dalian Enterprises " project, giving the application example of this research paper.Though research, this paper provides an information resource system description model for information integration in E-government, obtaining some research results of practical application value.
