Study On The Knowledge Management-based Enterprise Information System Architecture

At present , the society has come into a high speed development stage of information globalization and the seven seas informationization. Informationization change and knowledge innovation has become the central theme of the age. Thus the enterprises should strikes up a new enterprise development model which accommodates to the information society's competition demand. knowledge management-based enterprise information system architecture is just a brand practical and research area on information system developments that appears following the popularity of internet , the furthering of enterprise's informationization, the advancement information resources strategy status, the upsurge of electronic business and the rise of knowledge economics.As the integral part of national economy informationization, the enterprise informationization is the important approach to improve the modernization of business level and to enhance the enterprise competitive power. the developed country in the world is being in a stage that industry economy model is changing into information economy and knowledge economy, where the technology advancement ,particularly the information advancement play a very important role. As for enterprises ,adopting advanced information technology,quickening the electronic information technology development steps,adopting modern managerial approaches, developing and using enterprise management information system have been of necessity. in order to make the various management information systems achieve the expected results, we should fully considers architecture of the enterprise information system. However ,in the system development process of our country,the reason of focusing on technology,being short of planning ,ignoring the connection among institutional framework, staff and knowledge structure and wasting of resources is lacking of a scientific architecture of the enterprise information system.Implementing knowledge management is not only the demand for enterprises to adapt the society's developments but also the objective of enterprise informationization construction. banding the enterprise information system architecture and knowledge management together ,constructing a knowledge management-centered enterprise information system architecture is the development trend of enterprise information system architecture.the combination of the two makes knowledge management find out a carrier to bring it into play, and makes a qualitative leap for enterprise informationization.This thesis from the point of the gradual progress and climatic jump process of the enterprise's information system architecture practice activity, points out the significance of constructing knowledge management based enterprise information architecture. Firstly systematically studies enterprise information architecture's research achievements of both domestic and overseas,summarizes the theory basis, crucial technology and inherent laws of enterprise portal's gradual progress and climatic jump processes. On the above basis, guided by enterprise information system architecture construction's related theories , from the perspective of the knowledge management's application value in enterprise information architecture's construction,constructs the enterprise information system architecture's knowledge framework, knowledge repository, control part, implementation part and development part , develops a knowledge based enterprise information system architecture and explicates the function of knowledge based enterprise information system.The thesis covers six parts:The 1st Chapter is introduction. Starting with information system development process, points out that in order to achieve the expected results, the enterprise information system architecture should be fully considered. puts forward the constructing of knowledge management-based enterprise information system architecture is of great significance in both theory and practice, defines the research contents,research method and technique route.The 2nd Chapter is the research status of enterprise information system architecture both home and abroad, on the basis of summarizing the research results in enterprise information system architecture construction area, analyzes and reviews the research developments of enterprise information system architecture in both home and abroad .The 3rd chapter is the theory foundation and related technology of knowledge management-based enterprise information system architecture. From the point that The construction of information system architecture requires theory's guidance and technology's advancement, analyses reference value of theories such as knowledge management, information architecture and information resources integration, analyzes the application value of technology such as semantic web, business intelligence,agent Technology, intelligent in the construction of enterprise information system architecture.the 4th chapter is architecture of the enterprise system based on knowledge management. on the basis of analyzing the traditional enterprise information architecture's defects, from the angle of view that knowledge management's application in future enterprise management practice, constructs the knowledge management-based enterprise information system architecture, including knowledge framework of system architecture, knowledge repository, control parts, implementation parts and development parts,develops an enterprise information system architecture, and comprehensively explained the function of knowledge management-based enterprise information system.The 5th chapter is case analysis. on the basis of literature investigation and research,compares and studies the system architecture and function characteristics and summarizes the advantages and disadvantages of the typical enterprises system architectures both home and abroad.The 6th chapter is conclusion and outlook, gives the conclusion of this thesis and points out the problems to be resolved and the future study direction.
