The Research And Design Of EAI Model For Social Insurance Based On SOA

This paper analyses the problems of business and technology existing in the present taxation management of social insurance. A study is now made, concerning the way to solve the problems,the content and the goal of the critical technical problems. From the respect of the technology of the system information-integration, a data flow program of management and supervision between departments is designed. And with the technology of middleware and system architecture, the data exchange interface, data exchange criteria and the security policy are designed uniformly. Therefore, the system architecture of software and network are unified, the application of taxation management program is realized.As a new software architecture, SOA (Service Oriented Architecture) will soon replace the traditional software architecture in the information system of social insurance, of which distribution,modularization and standardization will be the definite trend. Therefore, the problems of information sharing of heterogeneous data and Enterprise Application Integration (EAI) exit in the process of construction,development and application of the information system of social insurance. So, with the theory of SOA, this paper discusses EAI and the theory of the information system of social insurance.Firstly, discussions are made on the realization of the key technology of EAI based on SOA, including the integration architecture of bus and star type,EAI of interface and server type etc., presenting a computing model which realizes the uniform description of key units, discovery and integrated distribution with Web Service.Secondly, this paper takes up the problems as follows: the problem of the realization of service-oriented EAI based on SOA, the centralization and distribution of data,the complexity of network and the particularity of this industry,the safety of data and network, the construction standard and criteria. By reuniting the business content,working routine,data flow and architecture of logical model , the problems of data conversion,trans-information,handling of business,news transmitting between the distributed and heterogeneous systems have been solved effectively.Lastly from the respects of system architecture,architecture of basic platform,data distribution,data exchange,data copy and etc, it expounds the standard definition of data exchange,the definition of mapping relation of the two exchange sides and the...
